Office of the Secretary

49 CFR Part 40

[Docket DOT-OST-2025-0049]
RIN 2105-AF26


Procedures for Transportation Workplace Drug and Alcohol Testing 
Programs: Addition of Fentanyl to the Department of Transportation's 
Drug-Testing Panel; Harmonization With Certain Items in the HHS 
Mandatory Guidelines for Urine and Oral Fluid; and Technical Amendments

AGENCY: Office of the Secretary of Transportation (OST), U.S. 
Department of Transportation.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The U.S. Department of Transportation (Department or DOT) 
proposes to amend its drug-testing program regulation, 49 CFR part 40 
(part 40), to add fentanyl (a synthetic opioid) and norfentanyl (a 
metabolite of fentanyl) to its drug testing panels. The proposed 
rulemaking would harmonize part 40 with the U.S. Department of Health 
and Human Services (HHS) Mandatory Guidelines for Federal Workplace 
Drug Testing Programs (Mandatory Guidelines), which DOT must follow for 
the minimum list of drugs for which DOT requires testing, and the 
comprehensive standards for laboratory drug testing per the Omnibus 
Employee Testing Act of 1991. Adding fentanyl and norfentanyl is also 
in the interest of transportation safety, given compelling information 
regarding the number of overdose deaths in the United States involving 
fentanyl. The Department also proposes to amend certain provisions of 
part 40 to harmonize, as appropriate, with the current HHS Mandatory 
Guidelines using urine (UrMG) and oral fluid (OFMG). This NPRM also 
proposes to clarify certain existing part 40 drug testing program 
provisions and to make technical amendments.

DATES: Comments to this notice of proposed rulemaking should be 
submitted by October 17, 2025. Late-filed comments will be considered 
to the extent possible.

SUPPLEMENTARY INFORMATION:

I. Purpose

    DOT requires urine drug testing and authorizes oral fluid drug 
testing as an alternative methodology to urine drug testing of safety-
sensitive transportation industry employees subject to drug testing 
under part 40 of Title 49 of the Code of Federal Regulations (part 40). 
DOT's part 40 regulations are in turn incorporated by reference in the 
drug and alcohol testing requirements of each of its operating 
administrations such that updates to part 40 automatically update the 
pertinent requirements of DOT's operating administrations.\1\
---------------------------------------------------------------------------

    \1\ See Sec.  40.3 (defining ``DOT, The Department, DOT Agency'' 
to include each of the DOT operating administrations).
---------------------------------------------------------------------------

    DOT is issuing this NPRM to harmonize part 40, as appropriate, with 
the revised HHS UrMG published on October 12, 2023 (88 FR 70768), the 
HHS OFMG published on October 12, 2023 (88 FR 70814), and the HHS 
Mandatory Guidelines for Federal Workplace Drug Testing Programs-
Authorized Testing Panels published on January 16, 2025 (90 FR 4662). 
The Department proposes to harmonize with these HHS Mandatory 
Guidelines because the Omnibus Transportation Employee Testing Act 
(OTETA) of 1991 requires DOT to incorporate the HHS scientific and 
technical guidelines that establish comprehensive standards for all 
aspects of laboratory testing of controlled substances to ensure full 
reliability and accuracy in testing. DOT also proposes to clarify 
certain existing part 40 drug testing program provisions and to make 
technical amendments.

II. Authority for This Rulemaking

    This NPRM is issued pursuant to OTETA of 1991 (Pub. L. 102-143, 
Tit. V, 105 Stat. 952). While DOT has discretion concerning many 
aspects of the regulations governing testing in the transportation 
industries' regulated programs, the Department must follow the HHS 
Mandatory Guidelines for the minimum list of drugs for which DOT 
requires testing and the standards for laboratory drug testing. Section 
503 of the Supplemental Appropriations Act, 1987 (Pub. L. 100-71, 101 
Stat 391, 468), 5 U.S.C. 7301, and Executive Order 12564 establish HHS 
as the agency that establishes scientific and technical guidelines for 
Federal workplace drug-testing programs and standards for certification 
of laboratories engaged in such drug testing.

III. Background

Relevant History of the DOT Drug Testing Program Regulation

    DOT first published its drug-testing program regulation, part 40, 
on November 21, 1988, as an interim final rule (53 FR 47002). The 
Department based the rule on HHS's April 11, 1988, Mandatory Guidelines 
for Federal Workplace Drug Testing Programs (See 53 FR 11970), which, 
in part, required Federal agencies to test employees for cocaine and 
marijuana. HHS based this requirement on the incidence and prevalence 
of the abuse of these two substances in the general population and on 
the experiences, at the time, of the Departments of Defense and 
Transportation in screening their workforces (See 53 FR 11970). 
Agencies also were authorized under the 1988 HHS Mandatory Guidelines 
to test for phencyclidine, amphetamines, and opiates. Among other 
provisions from those guidelines, DOT published a final rule on 
December 1, 1989 (54 FR 49854) that incorporated a 5-panel test with 
all of the drugs HHS authorized for testing.
    The Department made comprehensive revisions to part 40 on several 
occasions and harmonized with the HHS Mandatory Guidelines where 
necessary. For example, on August 16, 2010 (See 75 FR 49850), DOT 
harmonized with the HHS Mandatory Guidelines effective October 1, 2010 
(See 73 FR 71858; 75 FR 22809). Specifically, the Department required 
initial and confirmatory testing for methylenedioxymethamphetamine 
(MDMA), confirmatory testing for methylenedioxyamphetamine (MDA) and 
methylenedioxymethamphetamine (MDEA); and initial testing for 6-
acetylmorphine (6-AM). The Department also lowered the initial and 
confirmatory test cutoff concentrations for amphetamines and cocaine to 
conform with HHS changes. On November 13, 2017 (See 82 FR 52229), DOT 
harmonized with HHS Mandatory Guidelines effective October 1, 2017 (See 
82 FR 7920). Specifically, the Department required the initial and 
confirmatory testing for four additional Controlled Substances Act 
(CSA) Schedule II prescription opioid medications: hydrocodone, 
hydromorphone, oxycodone, and oxymorphone. DOT also removed MDEA as a 
confirmatory test analyte and added MDA as an initial test analyte from 
the existing drug-testing panel. On May 2, 2023 (See 88 FR 27596), the 
Department harmonized with the HHS OFMG effective January 1, 2020 (See 
88 FR 57554). Specifically, DOT amended part 40 to authorize oral fluid 
drug testing in the DOT drug testing program. This additional 
methodology for drug testing gives employers a choice that will help 
combat employee cheating on urine drug tests as oral fluid tests are 
inherently directly observed. Oral fluids testing provides a less 
intrusive means of achieving the safety goals of the program.

Relevant Changes to the HHS Mandatory Guidelines

    After declaring the opioid crisis a public health emergency in 
2017, the President signed the Substance Use-Disorder Prevention that 
Promotes Opioid Recovery and Treatment for Patients and Communities Act 
(SUPPORT Act) into law on October 24, 2018. Section 8105 of the 
Fighting Opioid Abuse in Transportation Act, included in the SUPPORT 
Act, required the Secretary of HHS to determine whether it is 
justified, based on the reliability and cost-effectiveness of testing, 
to revise the Mandatory Guidelines to include fentanyl.\2\ In addition, 
Section 8105 required the Secretary of HHS to consider whether to 
include any other drugs or other substances listed in Schedule I and II 
of section 202 of the Controlled Substances Act (CSA) (21 U.S.C. 
812).\3\

    Historically, when adding or removing drugs/analytes from the 
authorized drug testing panel, which was included in the HHS Mandatory 
Guidelines, HHS would publish ``proposed revised Mandatory Guidelines'' 
and after reviewing public comment and consulting with its Drug Testing 
Advisory Board (DTAB), publish ``revised Mandatory Guidelines.'' On 
April 7, 2022 HHS proposed (87 FR 20560; 87 FR 20522), and then revised 
on October 12, 2023, its UrMG (88 FR 70768) and OFMG (88 FR 70814), 
establish a new process for adding and removing drugs/analytes from its 
drug testing panel that would be more responsive to drug use trends, as 
well as provide flexibility based on the state of the science (e.g., 
new technologies and research including dosing studies). Using this new 
process, HHS would conduct a thorough review of the scientific and 
medical literature, solicit input from subject matter experts including 
DTAB, and provide an opportunity for public comment. Rather than 
publish the updated drug testing panels (i.e., drugs, analytes, and 
cutoffs) in the HHS Mandatory Guidelines, HHS would publish them 
annually or as necessary, in the Federal Register and post them on the 
HHS website. The drug testing panels are still part of the HHS 
Mandatory Guidelines by reference in Section 3.4 in both the UrMG and 
OFMG.
    Utilizing the new process described above, HHS issued a notice in 
the Federal Register on October 17, 2023 announcing a December 5, 2023 
DTAB meeting and agenda, which included a proposal to update the HHS 
drug testing panels to include fentanyl and norfentanyl (88 FR 71582). 
On November 17, 2023, HHS published a notice of correction to the 
October 17, 2023 notice stating that the DTAB Board would discuss the 
Mandatory Guidelines and the proposed revisions to the drug testing 
panels to (1) add fentanyl for urine and oral fluid and norfentanyl for 
urine, (2) remove MDMA and MDA, and (3) ask for public comment on its 
recommended changes to the authorized drug testing panels (88 FR 
80323). In both notices, HHS listed the proposed initial and 
confirmation cutoffs for fentanyl and norfentanyl in urine, listed the 
proposed initial and confirmation cutoffs for fentanyl in oral fluid, 
and asked for public comment on the proposed cutoffs.
    HHS said:
    Fentanyl accounts for a large proportion of overdose deaths in the 
United States and is therefore an important public safety concern. 
Furthermore, fentanyl is increasingly used as a stand-alone substance 
of abuse, not in conjunction with heroin and other substances as was 
common in the past. According to the National Forensic Laboratory 
Information System (NFLIS) 2021 report, fentanyl was the 4th most 
frequently identified drug and accounted for 11.61% of all drugs 
reported by forensic laboratories. Norfentanyl is an important 
component of identifying fentanyl users when urine is the specimen 
matrix. Fentanyl has been detected in oral fluid in pain management 
patients, overdose cases, and driving under the influence of drugs 
(DUID) cases. Information provided by HHS-certified laboratories in 
2023 indicated that a majority (84%) of the laboratories have 
previously analyzed non-regulated workplace specimens for fentanyl and/
or norfentanyl and that all had the ability to analyze urine specimens 
for fentanyl with sufficiently sensitive detection limits using 
commercially available immunoassay kits and confirmatory test

(footnote omitted).
---------------------------------------------------------------------------

    On November 1, 2023, DOT sent out a listserv notice \5\ informing 
employers, employees, and testing service providers involved in the DOT 
drug testing program of the upcoming DTAB meeting, and that the meeting 
agenda included a discussion regarding a possible update to the HHS 
analyte table to include fentanyl. DOT reminded the readers that it 
must follow the HHS scientific guidelines for DOT-regulated drug 
testing laboratory procedures, and that any change to the HHS analyte 
table may affect the DOT testing program under part 40, but only after 
DOT conducts its own conforming rulemaking. The listserv notice also 
stated that HHS was requesting public comment on the recommendation to 
add fentanyl and norfentanyl (along with their proposed testing 
cutoffs) to the analyte table and that comments could be submitted (1) 
prior to the DTAB meeting, (2) during the DTAB meeting, (3) up to 30 
days after the DTAB meeting, but no later than January 4, 2024, or (4) 
via email to HHS.

---------------------------------------------------------------------------

    On February 9, 2024, HHS published a notice announcing a March 5,

regarding the proposed changes to the analyte table, fentanyl 
prevalence, fentanyl immunoassay updates, cost and benefits analysis, 
and a summary of public comments received regarding the proposed 
changes to the HHS drug testing panels. As with the other DTAB-related 
notices discussed earlier, this notice discussed the reasons for adding 
fentanyl/norfentanyl and removing MDA and MDMA from the panel and 
requested public comment on the proposed changes. At the March 5, 2024 
open-session DTAB meeting, there were presentations on (1) the 
prevalence of fentanyl and norfentanyl in non-regulated specimens, (2) 
the availability of fentanyl and norfentanyl assays, (3) the costs of 
testing for fentanyl and norfentanyl, and (4) a summary of the public 
comments received regarding the proposed panel changes (i.e., addition 
of fentanyl and norfentanyl and removal of MDMA and MDA from the 
panel).\6\ There were 118 commenters and 176 comments received.\7\ The 
commenters included substance abuse professionals (SAPs), designated

---------------------------------------------------------------------------

    In a January 16, 2025 Federal Register notice (90 FR 4662), HHS 
added fentanyl (for urine and oral fluid) and norfentanyl (for urine 
only) to the authorized drug testing panels after (1) conducting 
studies to determine the prevalence of fentanyl in drug testing 
specimens, (2) examining the current state of the technology available 
to HHS-certified laboratories for initial and confirmatory testing for 
fentanyl and norfentanyl, (3) identifying and analyzing peer-reviewed 
publications that reported concentrations of fentanyl and/or 
norfentanyl in urine and oral fluid to help identify the appropriate 
testing cutoff concentrations, (4) requesting, receiving, and reviewing 
public comment, (5) conducting a cost analysis, and (6) considering 
input from DTAB.
    HHS also said that though they had proposed to remove MDMA and MDA 
from the drug testing panels due to the significantly low laboratory 
positivity rates, retain MDMA and MDA on the testing panels. This 
decision was based on HHS's review of all the comments to the docket. 
HHS said that removing MDMA and MDA from the testing panels was not 
warranted at this time, but that it will continue to monitor MDMA and 
MDA prevalence, assess the costs and benefits of removing one or both 
analytes in the future, and engage with DTAB on the issue.
    In the same Federal Register notice, HHS included separate tables 
with abbreviations for the drug analytes and required HHS laboratories 
and MROs to report results using this nomenclature. This was done for 
consistency and to avoid misinterpretations of test results. Specific 
to marijuana, the drug testing panels include revised abbreviations for 
the marijuana test analytes to be consistent with current scientific 
nomenclature. In the urine drug test panel, both the initial and 
confirmatory test analytes for marijuana were changed from THCA to 
[Delta]9THCC. In the oral fluid drug testing panel, both the initial 
and confirmatory test analytes for marijuana were changed from THC to 
[Delta]9THC. HHS also edited Footnote 1 in both drug testing panels to 
include more specific and updated criteria for alternate technology 
initial drug tests.
    In the latest revisions to the UrMG (effective February 1, 2024) 
and the OFMG (effective October 10, 2023), HHS also authorized 
laboratories to conduct biomarker testing in urine and oral fluid 
specimens after HHS approval and made edits to reflect this change 
(e.g., adding and defining the terms ``biomarker,'' ``biomarker testing 
panel,'' and ``drug testing panel,'' and revising the existing 
definition of ``substituted'' to address the change to report specimens 
as substituted based on biomarker testing). Once a biomarker test has 
been added to the HHS-authorized biomarker testing panel, HHS-certified 
laboratories may routinely conduct the test without requiring an MRO 
request, and only require a signed MRO request for case-by-case 
biomarker testing (in accordance with OFMG section 3.5). HHS continued 
to require the National Laboratory Certification Program (NLCP) to 
review biomarker assay validation records before allowing a laboratory 
to use the test for federally regulated workplace specimens.\9\ HHS 
will review and approve biomarkers based on submitted laboratory data 
and support from the scientific and medical literature, then will add 
approved biomarkers to the biomarker testing panel in a subsequent 
Federal Register notice. At the time of this NPRM, no biomarkers have 
been approved for Federal workplace drug testing.

---------------------------------------------------------------------------

    HHS also made other revisions to the UrMG \10\ and OFMG,\11\ 
including (1) revising the urine confirmatory test cutoff for morphine, 
(2) removing the additional decision point of 15,000 ng/mL for codeine

IV. Discussion of the Proposals

Summary of Proposed Changes to the DOT Drug-Testing Program Regulation

    In keeping with the Department's statutory obligation under OTETA 
of 1991 to incorporate the HHS Mandatory Guidelines specifically for 
the minimum list of drugs for which DOT requires testing, and for the 
scientific and technical guidelines related to laboratory testing 
procedures, the Department proposes to amend part 40 to (1) add the 
drugs fentanyl and norfentanyl and their respective cutoffs for initial 
and confirmatory testing (as listed in the HHS urine and oral fluid 
drug testing panels published in the Federal Register on January 16, 
2025, (90 FR 4662)) to the DOT drug testing panels (fentanyl would be 
added to both the urine and oral fluid testing panels, and norfentanyl 
to the urine testing panel); (2) adjust the laboratory confirmatory 
test cutoff for morphine in urine drug testing; (3) remove the MRO 
requirement to determine clinical evidence of illegal opioid use to 
support a positive codeine or morphine result in urine and oral fluid 
drug testing; (4) add and define the term ``biomarker'' and revise the 
definitions of ``adulterated specimen,'' ``cutoff,'' ``initial specimen 
validity test,'' ``negative result,'' ``positive result,'' and 
``substituted specimen'' for clarity and consistency with HHS; (5) 
authorize laboratories to conduct biomarker testing once HHS approves 
laboratory biomarker testing; (6) amend the analyte nomenclature for 
marijuana in both drug testing panels; and (7) revise the footnotes in 
both drug testing panels to include more specific and updated criteria 
for alternate technology initial drug tests. The Department will also 
provide clarification for certain existing drug testing program 
provisions and make certain technical amendments.
Proposal To Add Fentanyl and Norfentanyl to DOT Drug Testing Panels
    There are two types of fentanyl: pharmaceutical fentanyl and 
illicitly manufactured fentanyl. Both are considered synthetic opioids. 
Pharmaceutical fentanyl is prescribed by doctors to treat severe pain, 
especially after surgery and for advanced-stage cancer. Most cases of 
fentanyl-related overdose are linked to illicitly manufactured 
fentanyl,\12\ which is distributed through illegal drug markets for its 
heroin-like effect. It is often added to other illicit drugs because of 
its extreme potency, which makes those drugs cheaper, more powerful, 
more addictive, and more dangerous. Fentanyl is up to 50 times stronger 
than heroin and 100 times stronger than morphine. It is a major 
contributor to fatal and nonfatal overdoses in the U.S.\13\ Even in 
small doses, it can be deadly. Over 150 people die in the U.S. every 
day from overdoses related to synthetic opioids, primarily 
fentanyl.\14\

---------------------------------------------------------------------------

    The following is a representative sampling of information provided 
by various organizations that have reported on fentanyl use trends over 
the past few years:
     Drug overdose death rates involving fentanyl increased by 
279 percent from 5.7 per 100,000 in 2016 to 21.6 in 2021, according to 
new data from the CDC's National Center for Health Statistics 
(NCHS).\15\

---------------------------------------------------------------------------

     In 2022, the CDC's NCHS reported and predicted that the 
number of drug overdose deaths involving synthetic opioids (including 
fentanyl but excluding methadone) and psychostimulants with abuse 
potential (such as methamphetamine) continue to increase compared to 
the previous year.\16\

---------------------------------------------------------------------------

     According to the State Health Access Data Assistance 
Center (SHADAC), ``Not only has fentanyl become the dominant substance 
driving today's crisis of drug overdose deaths, but it also has become 
the center of gravity around which other drugs orbit.'' \17\

---------------------------------------------------------------------------

     According to the DEA, ``While recent data shows progress 
in reducing overdose deaths from record highs, nearly half of teens 
still don't know that counterfeit prescription pills often contain 
lethal amounts of fentanyl. This lack of knowledge is leading to tragic 
consequences--young people are dying simply because they didn't know 
the pill they took was fake. That's why we need to turn awareness into 
action.'' \18\

---------------------------------------------------------------------------

     ``While provisional data from the CDC indicates a 25.5% 
decrease in overdose deaths in the 12 months ending October 2024 
compared with the same period in 2023, approximately 150 Americans die 
every day from overdose involving illegal, synthetic opioids such as 
illegally made fentanyl. Overdose remains the leading cause of death 
among Americans aged 18-44. The Administration and HHS remain committed 
to preventing substance use initiation, reducing the number of lives 
lost to overdose, and helping Americans to overcome substance use 
disorders, achieve recovery, and live healthy lives.'' \19\

Carfentanil in Drug Overdose Deaths--United States, 2021-2024, 
https://www.cdc.gov/mmwr/volumes/73/wr/mm7348a2.htm.
---------------------------------------------------------------------------

    In light of this compelling information regarding fentanyl use (and 
the national attention on this issue), and consistent with the action 
taken by HHS, the Department proposes to amend the DOT drug testing 
panels to meet our statutory obligation under OTETA of 1991, and to 
raise the level of safety for the transportation industry and the 
transported public. Specifically, the Department proposes to amend the 
drug-testing panels in sections 40.85(a) and 40.91(a) to include 
fentanyl in the urine and oral fluid testing panel and norfentanyl to 
the urine testing panel (along with their corresponding test cutoff 
concentrations), amend the MRO verification process to include these 
drugs, and amend Appendices D and E of part 40 to add fentanyl and 
norfentanyl to the drugs listed on the laboratory reports to employers 
and DOT.

    Recognizing that the term ``opioid'' is used in a broad context to 
include various natural, synthetic, and semi-synthetic opioids, the 
Department proposes to modify its definition of ``opioid'' in section 
40.137 to remove the specific semi-synthetic compounds (i.e., 
hydrocodone, hydromorphone, oxycodone, and oxymorphone) and use the 
term ``opioids'' when referring to the opiates, synthetic opioids, and 
semi-synthetic opioid test results that an MRO may review and verify.
For Urine Drug Testing--Proposal To Adjust the Laboratory Morphine 
Confirmatory Cutoff and Remove the Additional Requirement for MROs To 
Look for Clinical Evidence of Illegal Opioid Use
    Currently, for a laboratory to report a positive codeine/morphine 
\21\ result for a urine specimen, the laboratory-confirmed result must 
be greater than or equal to 2,000 ng/mL.\22\ In our December 19, 2000 
final rule (65 FR 79462), the Department established a process to 
address a laboratory-reported positive result, which depends on the 
laboratory-reported codeine/morphine level. If the morphine level is 
between 2,000 and 15,000 the burden of proof is on the MRO, if the 
level is above 15,000 the burden of proof is on the employee. This 
process was established, in part, to address positive laboratory-
reported codeine/morphine results that may be due to poppy seed 
ingestion. Specifically, if the laboratory-reported codeine or morphine 
concentration for a urine specimen is greater than 2,000 ng/mL and less 
than 15,000 ng/mL, the MRO is required to examine the employee for 
clinical signs of unauthorized use or refer the employee to another 
physician for this purpose. In conducting the examination of the 
employee, the MRO or physician may consider such factors as needle 
tracks, behavioral or psychological signs of acute addiction, clinical 
history of unauthorized use including admissions by employees, or use 
of foreign opiate medication without substantiation that the medication 
was obtained and used legally.\23\ The MRO is to use his/her best 
professional and ethical judgment on a case-by-case basis. If the MRO 
finds clinical evidence, then the result is verified as ``positive.'' 
If the MRO does not establish that there is clinical evidence of 
unauthorized use of an opiate, then the result is verified as 
``negative.'' If the laboratory-reported codeine/morphine concentration 
is 15,000 ng/mL or greater, then the burden of proof falls on the 
employee to provide a legitimate medical explanation, which the 
employee may meet by showing that she or he had used a legally 
prescribed medication. When an employee cannot establish a legitimate 
medical explanation for codeine/morphine at or above 15,000 ng/mL, then 
the MRO verifies the test as positive.

---------------------------------------------------------------------------

    On April 7, 2022, HHS proposed revisions to its UrMG to (1) raise 
the confirmatory test cutoff for morphine in urine from 2,000 ng/mL to 
4,000 ng/mL and (2) remove the additional requirement for clinical 
evidence of illegal opioid use to verify laboratory-reported positive 
codeine/morphine results less than 15,000 ng/mL as positive (87 FR 
20560). Regarding morphine cutoff levels, HHS stated that it had 
reviewed several studies and concluded that those studies ``. . . 
confirm that urine morphine concentrations exceeding 4,000 ng/mL would 
be very rare, transient, and a consequence of unrealistic and extreme 
poppy seed exposure (i.e., ingesting barely tolerable amounts of raw 
and/or unwashed poppy seeds).'' HHS also cited the DEA's 2019 warning 
about unwashed poppy seeds from online retailers, which stated ``. . . 
their use and misuse may result in unpredictable outcomes including 
death when used alone or in combination with other drugs. DEA 
reiterated that morphine and codeine, if present as contaminants on 
poppy seed material, are not exempted from Controlled Substances Act 
(CSA) control.'' HHS concluded that ``. . . the Department is not aware 
of any evidence that reasonable or realistic consumption of poppy seed-
containing food products would cause a positive drug test using the 
codeine and morphine cutoffs specified by these Guidelines. Only 
purposeful consumption of large amounts (e.g., 15 g or more) of raw 
and/or unwashed poppy seeds has been shown to result in codeine at or 
above 600 ng/mL or in morphine exceeding 4,000 ng/mL, and the extreme 
amounts of poppy seeds in these studies, described by subjects as 
intolerable or barely tolerable, do not represent a real-world 
situation for donors in a Federal agency testing program.'' Based on 
its review of existing research, which did not show that reasonable or 
realistic consumption of poppy seed-containing products would cause a 
positive urine drug test result for codeine at the established cutoff 
of 2,000 ng/mL, HHS did not propose to adjust the cutoff level for 
codeine in urine.
    As mentioned above, the requirement to look for clinical evidence 
of illegal opioid use to verify laboratory-reported positive codeine/
morphine results of less than 15,000 ng/mL (for urine) was established 
to address positive laboratory-reported codeine/morphine results that 
may be due to poppy seed ingestion. Because HHS has now identified a 
morphine cutoff level at which reasonable or realistic consumption of 
poppy seed-containing products would not trigger a positive urine drug 
test result, and because the existing codeine cutoff level would also 
not trigger a positive urine drug test result, HHS has removed the 
requirement for MROs to look for clinical evidence of illicit opiate 
use as a decision point on whether to report a urine codeine/morphine 
result as negative or positive due to poppy seed ingestion.
    In its October 2023 revised UrMG effective February 1, 2024, HHS 
adjusted only the confirmatory test cutoff for morphine from 2,000 ng/
mL to 4,000 ng/mL and removed the requirement for clinical evidence of 
illegal opioid use to verify laboratory-reported positive urine 
codeine/morphine results less than 15,000 ng/mL as positive as 
proposed. HHS said that it had received one comment agreeing with the 
proposed change. HHS made these changes following a notice and 
opportunity for public comment.
    Because DOT's laboratory drug testing procedures must remain 
consistent with the HHS UrMG as required by OTETA of 1991, the 
Department proposes to amend the urine drug testing panel in section 
40.85 by adjusting the morphine confirmation cutoff from 2,000 ng/mL to 
4,000 ng/mL and propose to remove the word ``concentrations'' from the 
header in the table to be consistent with the terminology in the HHS 
urine drug testing panel. Because the proposed morphine cutoff is at a 
level at which reasonable or realistic consumption of poppy seed-
containing products would not trigger a positive urine drug test 
result, and because the existing codeine cutoff level would also not 
trigger a positive urine drug test result, there is no need for an 
additional decision point (i.e., clinical evidence of illegal opioid 
use). Therefore, the Department proposes to remove the additional 
requirement in section 40.139 for a clinical exam to identify evidence 
of illicit opiate use as a decision point on whether to report a 
codeine/morphine result as negative or positive due to poppy seed 
ingestion. Instead, DOT

[[Page 42368]]

proposes that MROs follow the existing verification process outlined in 
section 40.137. Accordingly, the Department proposes to modify section 
40.137 to include the verification of opiates (6-AM, codeine, and 
morphine) previously found in section 40.139.
    In further support of this proposal, the Department has heard from 
MROs anecdotally that they have difficulty finding a physician to 
complete the required clinical examination and that a majority of those 
examinations result in the MRO verifying the result as ``negative.'' 
Based on calendar year 2023 data from four HHS-certified laboratories 
(which conduct approximately 44 percent of the annual DOT tests), 
approximately 1,782 of the 6.8 million drug tests administered in the 
DOT program were reported with morphine results between 2,000 ng/mL and 
15,000 ng/mL (899 tests were between 2,000-4,000 ng/mL, and 883 tests 
were between 4,000-15,000 ng/mL). By adjusting the urine morphine 
confirmation cutoff in part 40, and by removing the requirement for 
clinical evidence of illegal opioid use for laboratory-reported 
positive codeine/morphine results less than 15,000 ng/mL, the 
Department expects that MROs will be better able to verify laboratory-
reported urine codeine/morphine results.
For Oral Fluid Drug Testing--Proposal To Remove Additional Requirement 
for MROs To Look for Clinical Evidence of Illegal Opioid Use
    In the OFMG effective January 1, 2020, HHS established a 
confirmatory cutoff of 15 ng/mL for both codeine and morphine for 
laboratories to report a laboratory-confirmed positive result and a 
codeine/morphine level of 150 ng/mL (10 times that of the confirmatory 
test cutoff) as a conservative decision point for MROs to rule out the 
possibility of a positive result due to poppy seed consumption. HHS 
noted that ``the 150 ng/mL concentration is higher than the highest 
concentration seen in study subjects at one hour and later after 
consumption of raw poppy seeds and products containing poppy seeds.'' 
\24\ In its OFMG effective October 10, 2023, HHS maintained the 
confirmatory cutoff of 15 ng/mL for both codeine and morphine for 
laboratories to report a laboratory-confirmed positive result. HHS also 
maintained a codeine/morphine level of 150 ng/mL). The MRO must report 
a codeine/morphine result at or above 150 ng/mL as ``positive'' unless 
the employee provides a legitimate medical explanation for the result.
---------------------------------------------------------------------------

    \24\ https://www.govinfo.gov/content/pkg/FR-2019-10-25/pdf/2019-22684.pdf (pg. 57559).
---------------------------------------------------------------------------

    HHS removed the requirement for the MRO to conduct a clinical 
examination (i.e., physical examination) for laboratory-reported oral 
fluid results between 15 ng/mL and 150 ng/mL when the donor claimed the 
result was due to poppy seed consumption. In these cases, the MRO 
reports the result as ``negative'' unless the employee admits illicit 
use. As explained in the HHS April 7, 2022 proposed OFMG (87 FR 20522), 
MROs routinely conduct donor interviews by telephone, rather than in-
person, and some MROs had expressed concern about the feasibility of 
making a clinical assessment (i.e., physical examination) of the donor. 
HHS concluded that the additional requirement for clinical evidence of 
illegal opioid use in these situations was no longer practical or 
effective. HHS adopted the proposed revisions with no changes in the 
October 2023 revised OFMG.
    DOT proposes to harmonize with HHS on this point as well. Given 
that HHS has established a ``bright line'' for codeine/morphine results 
of 150 ng/mL (having determined that results above this level cannot be 
caused by the ingestion of poppy seed products and that results below 
this level are those that MROs are most likely to report a ``negative'' 
result based on a clinical exam), the Department does not see the need 
for an additional decision point (clinical evidence of illegal opioid 
use) to rule out codeine/morphine results that may have been due to 
ingestion of poppy seed products. Therefore, the Department proposes to 
remove the requirement for the MRO to conduct a clinical exam if the 
result is at or above 15 mg/mL and less than 150 ng/mL, and to report 
codeine/morphine levels between 15 ng/mL and 150 ng/mL as ``negative'' 
when the employee claims poppy seed ingestion. If the employee does not 
claim poppy seed ingestion (and for all other codeine/morphine 
results), the Department proposes that MROs follow the existing 
verification process outlined in section 40.137.
    Because the Department is proposing for an MRO to report a 
``negative'' when the oral fluid codeine/morphine oral fluid results 
are at or above 15 mg/mL and less than 150 ng/mL when the employee 
claims poppy seed ingestion, the Department is therefore also proposing 
to amend section 40.151(d) to include an exception for laboratory 
positive codeine or morphine, or both, results. Currently paragraph (d) 
instructs the MRO not to consider an employee's claim of passive or 
unknown ingestion stories as a legitimate medical explanation.
    Since the Department is proposing to remove the requirement for 
MROs to look for clinical evidence of illegal opioid use in codeine/
morphine results in urine and oral fluid specimens, and instead follow 
the process outlined in section 40.137, there is no need for section 
40.139. The Department therefore proposes to move the verification of 
6-AM results from section 40.139 to section 40.137 and to remove the 
remaining section 40.139 in its entirety. DOT specifically seeks 
comments from MROs on these issues.
Proposal To Add Biomarkers for Urine and Oral Fluid Testing
    A biomarker is an endogenous substance used to validate a 
biological specimen. The purpose of a biomarker test is to determine if 
the submitted specimen is a human urine or oral fluid specimen as there 
are many ways a DOT-regulated transportation employee could effectively 
mask illicit drug use. In essence, a biomarker test is a specimen 
validity test (SVT). In the October 2023 revisions to the UrMG, HHS 
adopted its proposed changes to modify the definition of ``substituted 
specimen'' to include biomarker test results as an additional reason 
indicating that a specimen has been submitted in place of an actual 
donor specimen, and the process for adding biomarkers as well as 
including them in a biomarker testing panel. HHS adopted procedures to 
allow for review and comment before any biomarker panel change is 
published in the Federal Register. If a laboratory identifies and 
validates a biomarker test and submits it to HHS for approval, HHS will 
follow its established process for ensuring the test result is 
scientifically valid and forensically defensible. A laboratory can only 
conduct biomarker testing once approved by HHS and the biomarker is 
added to the authorized biomarker panel. HHS has not made biomarker 
testing mandatory.
    Consistent with HHS's April 2004 (69 FR 19644) \25\ amendments to 
make SVT mandatory for Federal employee testing under the HHS Federal 
Workplace Drug Testing Program, the Department made SVT on DOT urine 
specimens mandatory in 2008 as an appropriate response to the use of 
adulterants and attempts to subvert the specimen collection and 
laboratory testing process. (73 FR35961).\26\ The

[[Page 42369]]

widespread availability of various adulteration and substitution 
products has not changed since then, and DOT believes that more 
products are available, including information and online personal 
testimonials from individuals who have used those products. A simple 
internet search for ``how to beat a drug test'' yields hundreds, if not 
thousands, of results. Any individual who intentionally tries to ``beat 
a drug test'' is of significant concern to transportation safety and 
the traveling public. That said, the drug testing process is in place 
to ensure that individuals can perform their job functions safely and 
effectively, and do not subvert drug testing procedures that help 
ensure public safety.

---------------------------------------------------------------------------

    Given that the purpose of a biomarker test--a laboratory standard 
for drug testing--is to determine if the submitted specimen is a human 
specimen, the Department proposes to harmonize with HHS to include 
biomarker testing as an additional component of SVT for urine. The 
Department realizes that as biomarker tests are developed by individual 
laboratories, approved by HHS, and added to HHS's biomarker panel(s), 
not all laboratories may have the technical capability to conduct 
biomarker testing and, therefore, will not offer that testing. 
Therefore, the Department thinks it is prudent to wait until more 
laboratories have the technical ability to conduct biomarker testing 
before making it mandatory for DOT testing. Like HHS, DOT will not 
propose to make biomarker testing mandatory in either urine or oral 
fluid at this time. DOT proposes to amend sections 40.86, 40.87, and 
40.88 to authorize biomarker testing in urine. Though DOT has already 
authorized SVT for oral fluid specimens (See section 40.92), the 
Department will clarify that SVT testing may include testing for 
biomarkers. DOT also proposes to amend section 40.93 by removing 
albumin or immunoglobulin G (IgG) as examples of biomarkers. Though 
they serve as examples, the Department, like HHS, is removing them 
because there is a process HHS established to have biomarkers approved 
and DOT does not want to mislead anyone into thinking that they are 
approved biomarkers for testing. Furthermore, DOT proposes to harmonize 
with HHS to amend the definition of ``substituted specimen'' in section 
40.3, add a definition for ``biomarker'' in the same section, and 
require a laboratory to report a ``substituted'' result when a 
biomarker is absent or when its concentration is not consistent with 
that established for human urine. However, DOT does not propose to 
include a biomarker testing panel in part 40, but simply to refer to 
HHS's published biomarker panel as reference in the Mandatory 
Guidelines. The Department welcomes comments on this issue.
    Because the Department proposes to amend the definition of 
``substituted specimen'' to include the results of a urine or oral 
fluid biomarker test, DOT also proposes to amend an existing procedural 
safeguard for employees in the MRO review process for laboratory-
reported substituted results. Specifically, in section 40.145, DOT 
proposes to include a biomarker test result as a test result for which 
the employee can provide medical evidence to the MRO that the employee 
can produce a specimen without the presence of a specific biomarker 
when one is expected in a human specimen, or a specimen with a 
biomarker concentration that is not consistent with that established 
for human specimens.
Proposal To Add and Revise Definitions
    The Department proposes to modify some existing definitions and add 
a new term to section 40.3 to align more closely with definitions in 
the revised HHS Mandatory Guidelines. DOT welcomes your comments on 
these proposed changes. Specifically, the Department proposes to revise 
the following definitions, consistent with the HHS definitions:
     Adulterated specimen revised to include ``nitrite'' as an 
example of a substance present in urine that will cause a laboratory to 
report an adulterated result;
     Cutoff revised to include ``biomarkers'' as criteria used 
in the decision for the laboratory in reporting a specimen result or 
the need for further testing;
     Initial specimen validity test revised to state that a 
``dilute'' result is applicable only to a urine specimen;
     Negative result revised to include the text ``drug 
metabolite.'' This is to clarify that a drug or drug metabolite, or 
both, is either not present or less than the cutoff concentration for 
the drug or drug metabolite;
     Positive result revised to clarify that the quantity of 
drug reported by the laboratory is equal to or greater than the 
confirmatory test cutoff. This should help to alleviate any 
misunderstanding that the final result is not based on the initial test 
cutoff, but on the confirmatory test cutoff; and
     Substituted specimen revised to clarify that a urine or 
oral fluid specimen can also be reported as substituted based on 
evidence of either the absence of a biomarker or a biomarker 
concentration inconsistent with that of a human specimen.
    The Department proposes to add the following definition:
     Biomarker is an endogenous substance used to validate a 
biological specimen.
Proposal To Amend Nomenclature for Marijuana and Amend Drug Testing 
Panel Footnotes
    In the urine and oral fluid drug testing panels, HHS revised the 
drug analyte name and abbreviation nomenclature specifically for the 
marijuana metabolite. The change was made to be consistent with current 
scientific nomenclature. In the urine drug test panel, both the initial 
and confirmatory test analytes for marijuana were changed from THCA to 
[Delta]9THCC. In the oral fluid drug testing panel, both the initial 
and confirmatory test analytes for marijuana were changed from THC to 
[Delta]9THC. The oral fluid drug testing panel does not identify the 
THCA metabolite as in the urine drug testing panel, but identifies the 
active [Delta]9THC analyte. This nomenclature change does not affect 
the testing process for marijuana, but instead, just affects how 
laboratories and MROs are to refer to the marijuana analyte. Also, 
based on current technology and program experience, HHS revised 
Footnote No. 1 to both drug testing panels to include more specific and 
updated criteria for alternate technology initial drug tests. In 
keeping with the OTETA of 1991 requirement to incorporate HHS 
laboratory standards, the Department proposes revising the drug testing 
panels in sections 40.85 and 40.91 to harmonize with HHS by 
incorporating this nomenclature change for marijuana and the revisions 
in Footnote No. 1.
Other Proposals
Section 40.14 What collection information must employers provide to 
collectors?
    As discussed in the May 2023 final rule, section 40.40(c)(2) no 
longer mandates that fax numbers be included on the chain of custody 
form (CCF). Sections 40.14(d) and (f), however, require the employer to 
provide employer and MRO fax numbers to the collector. This was an 
oversight, and the Department proposes to correct section 40.14 to be 
consistent with section 40.40. Specifically, in sections 40.14(d) and 
(f), DOT proposes to amend the text to make providing the employer and 
MRO fax numbers to the collectors optional.

[[Page 42370]]

Section 40.25 Must an employer check on the drug and alcohol testing 
record of employees it is intending to use to perform safety-sensitive 
duties?
    The Department proposes to fix an incorrect reference in section 
40.25(a)(2), which states that as `` . . . an employer regulated by 
FMCSA, you must comply with the requirements of this section by using 
the FMCSA's Drug and Alcohol Clearinghouse in accordance with 49 CFR 
382.71(a).'' That reference should read section 382.701(a), and not 
section 382.71(a). Also, in section 40.25(b)(5), DOT directs employers 
to request certain drug and alcohol information about a prospective 
employee seeking to begin performing safety-sensitive duties. Though 
the Department did not specify in (b)(5) all the documents relating to 
the return-to-duty requirements, these documents include two SAP 
reports (the initial assessment report and the follow up evaluation, 
which also includes the follow up testing plan), the return-to-duty 
test result(s), and the completed follow up test results. DOT is 
proposing to amend (b)(5) by listing these documents so employers know 
what documents they need to obtain so they can verify that the 
prospective employee has completed the DOT return-to-duty requirements.
Section 40.31 Who may collect specimens for DOT drug testing?
    As discussed in the preamble to the May 23, 2023 final rule, and 
consistent with numerous other deletions of the term ``urine'' in 
instances where the rule was intended to cover both urine and oral 
fluid specimens, the Department amended section 40.31 to separately 
specify the requirements for collectors of urine and oral fluid 
specimens. In doing so, DOT did not remove the word ``urine'' from 
paragraph (a). Also, DOT believes that paragraphs (b) and (c) should be 
subparagraphs to paragraph (a). As such, the Department is proposing to 
remove the word ``urine'' from paragraph (a) and redesignate (b) and 
(c) to be subparagraphs (a)(1) and (a)(2) respectively and redesignate 
paragraphs (d) to (b), (e) to (c) and (f) to (d).
Section 40.33 What training requirements must a urine collector meet 
for urine collection?
Section 40.35 What training requirements must an oral fluid collector 
meet for oral fluid collection?
Section 40.213 What training requirements must STTs and BATs meet?
    Over time, the Department has heard from associations and 
individual trainers suggesting that the program and collectors (for 
urine and oral fluid) would greatly benefit if both the qualification 
training and the initial proficiency demonstration were completed 
within 30 days of the completing the qualification training. They also 
suggested that if an individual cannot complete the entire training 
within 30 days, the individual re-take the qualification training. The 
associations and trainers said that the longer the timeframe between 
the qualification training and the mock collections (i.e., the initial 
proficiency demonstration), the more the trainee will forget the part 
40 required procedures, making it harder for the trainee to demonstrate 
proficiency during the mock collections. They also pointed out that the 
``Breath Alcohol Technician Training: DOT Model Course'' already has 
this standard as a recommendation. Specifically, the model course 
recommends that: (1) individuals arrange to take the procedural and 
device proficiency training simultaneously, (2) the entire training 
process should be completed within 30 days, and (3) the individual be 
required to retake the procedural training program if the student has 
not completed the device proficiency training within 30-days of the 
start of the qualification training.
    The Department agrees that the closer in time the qualification 
training and initial training proficiency are completed, the greater 
the retention of information and the greater the chances of 
successfully completing the initial proficiency demonstration. As a 
program, the Department wants only those qualified to be collectors and 
Screening Test Technicians (STT)/Breath Alcohol Technicians (BAT) to 
collect specimens and administer alcohol tests. The Department also 
agrees that this should be the standard for all collectors and alcohol 
test technicians (i.e., urine collectors, oral fluid collectors, 
screening test technicians, and breath alcohol technicians). With the 
above in mind, DOT proposes to amend sections 40.33, 40.35, and 40.213 
to include a 30-day timeframe within which the qualification training 
and initial proficiency demonstration must be completed when an 
individual becomes qualified as a collector or alcohol technician, or 
both, for the first time. There will be no additional costs associated 
with this proposal as the qualification training and initial 
proficiency demonstration are already required. The Department is not 
proposing, however, that the 30-day timeframe also apply to when the 
oral fluid collector or alcohol technician, or both, seek to qualify on 
a second device. Because they have already demonstrated proficiency in 
part 40 when they first became qualified, they will only need to 
complete mock collections that demonstrate proficiency on the ``new-
second'' device they will be using.
Section 40.35 What training requirements must a collector meet for oral 
fluid collection?
    As stated above, the Department paralleled the oral fluid collector 
qualifications in section 40.35 as closely as possible to our existing 
urine collector qualifications in section 40.33. Regarding the mock 
collection scenarios specified in section 40.33(c)(1), one scenario is 
the employee refuses to sign the CCF and initial the specimen bottle 
tamper-evident seal. In the Department's May 2023 final rule (88 FR 
27596), DOT included the first part of the scenario (refusing to sign 
the CCF) but inadvertently left out the second part (refusing to 
initial the specimen bottle tamper-evident seal). The Department 
proposes to correct this omission.
    Also in the May 2023 final rule, DOT amended section 40.33(f) to 
not require error correction training for a urine collector when a test 
was cancelled for circumstances that are beyond the control of the 
collector. For example, when a specimen is damaged by a delivery truck 
or is lost in transit. DOT intended to mirror this amendment in section 
40.35(f) for oral fluid collectors as it made sense that similar 
situations could happen with oral fluid specimens and the oral fluid 
collector should not be held accountable for those errors. To ensure as 
much consistency as possible, between the urine and oral fluid 
collector training requirements and to not burden the oral fluid 
collector with unnecessary error correction training, the Department is 
proposing to amend section 40.35(f) to not require error correction 
training for an oral fluid urine collector when a test is cancelled for 
circumstances that are beyond the control of the collector.

[[Page 42371]]

Section 40.61 What are the preliminary steps in the collection process?
    Part 40 is clear when the employer is responsible for determining 
if a refusal to test occurred. For example, with respect to 
collections, the collector documents what happened at the collection 
site and provides the employer with the information for the employer to 
make a final decision about whether the employee's conduct constitutes 
a refusal to test (See sections 40.191(d)(1)) and 40.355(i)). Section 
40.61(f), however, provides incorrect instructions for the specimen 
collector when an employee fails to comply with the collector's 
directions. Specifically, it directs the collector to advise the 
employee that failure to comply with the collector's directions 
constitutes a refusal to test. This is inconsistent with other sections 
of part 40 that, in similar circumstances, direct the collector to stop 
the collection, note the circumstances on the CCF, and report the 
information to the employer/DER to make the refusal determination. To 
the maximum extent practicable, to provide for uniformity and 
consistency in the requirements for urine and oral fluid testing 
throughout part 40, the Department proposes to remove the last sentence 
in section 40.61(f) and mirror section 40.72(b)(2), stating the 
collector must terminate the collection, note the circumstances in the 
Remarks section of the CCF, and report the information to the DER as 
described in section 40.191(a)(8) (failure to cooperate) so that the 
employer can decide whether to deem the situation a refusal. Except for 
section 355(j), a service agent should not be determining a refusal 
that may have part 40 and DOT agency consequences; this is the purview 
of the employer.
Section 40.65 What does the collector check for when the employee 
presents a urine specimen?
    Part 40 authorizes an employer to use oral fluid specimen 
collections. For problematic urine collections (e.g., insufficient 
specimen), section 40.193(a) authorizes the employer to either continue 
with the original specimen type (urine) for the second collection, or 
to continue with an alternate specimen type (oral fluid). Section 
40.65, however, instructs the urine collector that, in the event of an 
insufficient urine specimen, the collector is to follow the ``shy 
bladder'' procedures in section 40.193(b), which instruct the collector 
to collect another urine specimen. This is contrary to the instructions 
in section 40.193(a) that offer the employer the choice of continuing 
with a urine specimen or to move to an oral fluid specimen. Therefore, 
the Department proposes to revise the incorrect reference to have 
section 40.65(a)(1) read ``If it does not, you must follow the 
procedures in 40.193(a).''
Section 40.72 What steps does the collector take in the collection 
process before the employee provides an oral fluid specimen?
    In section 40.72(b)(2), the Department proposes to correct a 
typographical error. Specifically, at the end of the paragraph, the 
last word ``refusal'' should read ``refusal to test.''
Section 40.73 How is an oral fluid specimen collected?
    In Sec.  40.73(c)(4), DOT requires an oral fluid collector to 
collect a second oral fluid specimen if it is apparent to the collector 
that the employee tampered with the first specimen. The logical 
progression would be for the oral fluid collector to complete the first 
specimen collection, prepare it for shipment to the laboratory, 
immediately begin a second oral fluid specimen collection, and send 
both specimens to the laboratory. The instructions in section 
40.73(c)(4), however, only tell the collector to collect a second 
specimen and are currently silent as to what to do with the tampered 
first specimen. The Department proposes to correct this ``gap'' by 
including supplemental instructions for the collector to complete the 
first collection and to send both specimens to the laboratory. In this 
same section, there are no instructions regarding what a collector is 
to do if the donor refuses to provide a subsequent oral fluid specimen 
due to tampering with their first specimen. Therefore, the Department 
proposes to add a new subparagraph to (c)(4)(iii) instructing the 
collector to discard any specimen the employee provided during the 
specimen collection procedure, and to notify the DER as soon as 
practicable so the employer can determine whether the situation 
constitutes a refusal to test by the employee. Both proposals are 
consistent with existing part 40 procedures for urine specimen 
collections (See section 40.65(c)).
Section 40.83 How do laboratories process incoming specimens?
Section 40.199 What problems always cause a drug test to be cancelled?
    HHS added a new ``fatal flaw'' to its OFMG specifying that the 
laboratory must reject an oral fluid specimen when a collector fails to 
document that she or he observed the volume indicator at the time of 
the collection. (88 FR 70814) \27\ HHS's basis for this amendment was 
that the oral fluid specimen volume is critical to determining specimen 
concentration, therefore the collector must document that she or he 
observed the volume indicator at the time of the collection. The 
Department agrees with this important procedural check, and therefore 
proposes to amend sections 40.83(c) and 40.199(b) to add this new 
``fatal flaw'' in each section.

---------------------------------------------------------------------------

Section 40.141 How does the MRO obtain information for the verification 
decision?
    MROs are authorized to ask HHS certified labs to run additional 
drug tests on a case-by-case basis and use the results of those tests 
to provide information that the MRO would use to verify a drug test 
result. These additional tests included D, L stereoisomers of 
amphetamine and methamphetamine (for amphetamine results) and 
tetrahydrocannabivarin (THC-V) (for marijuana results). In its October 
2023 OFMG, HHS did not include testing for THC-V as it relates to oral 
fluid drug testing because in oral fluid drug testing the test is for 
active THC, the parent drug, and not for the THCA metabolite. Because 
the oral fluid test is for the parent drug, THC, there is no question 
that the employee ingested marijuana and no need for additional 
testing. The Department agrees and proposes to clarify in section 
40.141(b)(2) that the MRO's request for additional testing for 
tetrahydrocannabivarin (THC-V) would only apply to urine specimens.
Section 40.181 What does the second laboratory do with the split 
specimen when it is tested to reconfirm a substituted test result?
    In both the UrMG and OFMG, HHS added procedures for how a 
laboratory tests a split specimen when the primary specimen was 
reported substituted based on testing for a biomarker. As such, the 
Department is proposing to amend section 40.181 to provide instructions 
to the ``B'' laboratory on how to test a urine or oral fluid specimen 
when testing the split specimen for biomarkers.
    When it comes to what action a laboratory and MRO must take when a 
split is identified as substituted, the Department looks to section 
40.187(b)(2). Should biomarker testing be authorized, laboratories and 
MROs would need instructions on how to proceed if the split specimen 
was

[[Page 42372]]

reported substituted based on biomarker testing. The Department 
believes section 40.187(b)(2) contains the necessary instructions for 
laboratories and MROs and does not propose to amend it. DOT 
specifically requests comments from MROs and laboratories on this 
issue.
Section 40.193 What happens when an employee does not provide a 
sufficient amount of specimen for a drug test?
    In Sec.  40.193(a) the Department proposes to add the words ``or 
standing orders'' after the word ``instructions.'' This is to ensure 
consistency with section 40.210, which instructs the collector to 
follow the employer's instructions, which could be via a discussion or 
``standing orders'' when a decision needs to be made on whether a 
different specimen type is to be collected during the testing event.
    The Department is also proposing to amend section 40.193(b)(2) by 
adding two sets of instructions for the oral fluid collector. The first 
proposal is to discard any insufficient specimen the employee provided 
that had unusual characteristics or signs of tampering (See section 
40.73(c)(4)), which results in a subsequent oral fluid specimen 
collection where the employee fails to provide a sufficient oral fluid 
specimen after the one hour wait period. Regarding this proposal, it 
makes sense to rely solely on the outcome of the insufficient specimen 
process (See section 40.193(c)) as the intent of the ``dry mouth'' 
evaluation is to provide the employee with an opportunity to provide an 
explanation for the inability to provide a sufficient oral fluid 
specimen. In the insufficient specimen process, an MRO with advice from 
a referral physician determines whether a medical condition has, or 
with a high degree of probability could have, precluded the employee 
from providing a sufficient amount of specimen. This rationale becomes 
blurred with a verified drug test result from the same collection 
event. The reasoning for discarding the insufficient ``suspect'' 
specimen is simple. It should reduce opportunities for confusion by the 
collector on whether to send an insufficient ``specimen'' to the 
laboratory when the employee did not provide a sufficient specimen 
after the one hour wait period and will leave the MRO to report only 
the outcome of the ``dry mouth'' evaluation. This proposal is 
consistent with the existing part 40 instructions for urine collectors 
during the ``shy bladder'' period (See section 40.193 (b)(1)(iv)).
    The second proposal is to include instructions in section 
40.193(b)(2) for the oral fluid collector to discontinue the collection 
if the employee refuses to provide a subsequent specimen and to notify 
the employer of the refusal event. The Department is proposing this 
because this section does not address this possibility. This proposal 
is consistent with the existing part 40 instructions for urine 
collectors during the ``shy bladder'' period (See section 40.193 
(b)(1)(iii)).
    In the Department's May 2023 final rule, DOT established a 15-
minute period during which the employee is permitted to attempt to 
provide a sufficient oral fluid specimen, codified in 49 CFR 
40.193(b)(2)(i). If the employee does not provide a sufficient 
specimen, the oral fluid collector will again attempt to collect a 
sufficient specimen. DOT established the 15-minute wait period based on 
the HHS OFMG (84 FR 57554). According to HHS, the collector sets the 
reasonable time limit for the specimen collection (based on the device 
used, but not to exceed 15 minutes (per device)). It was our 
understanding that the 15-minute period was more of a general rule, and 
not device-specific. The Department has since learned that for at least 
one specific oral fluid collection device that has been approved by the 
Food and Drug Administration (FDA), the 15-minute period exceeds that 
device's instructions on the specified period (10 minutes) in which to 
collect a sufficient specimen. The Department understands that 
exceeding that device's timeframe for collecting a sufficient specimen 
would not in and of itself cause the device to fail, but doing so could 
potentially expose the device to unintentional tongue or other oral 
movement that may end up breaking or tearing the pad. The Department 
has also learned that for this specific device, if the volume indicator 
does not register a sufficient volume during the 10-minute period, 
waiting an additional 5 minutes will not result in the device 
registering a sufficient volume. The Department expects that other oral 
fluid devices will eventually be approved, and that those other devices 
may have different specimen collection timeframes. To ensure the 
timeframe in which oral fluid specimens are being collected in 
accordance with the device manufacturer's instructions, the Department 
proposes to amend section 40.193(b)(2)(i) to remove the 15-minute 
period, and instead refer to the manufacturer's instructions.
Section 40.311 What are the requirements concerning SAP reports?
    Section 40.329(c) directs the SAP to redact the follow-up testing 
plan from the SAP report when providing the report to an employee. 
Section 40.311(f) directs the SAP to provide the SAP reports to the 
employee if the employee has no current employer but makes no mention 
of redacting the follow up testing information as stated in section 
40.329(c). Without a cross-reference to section 40.329(c), it may lead 
the SAP or the employee to believe that the reports in their entirety 
are to be provided.
    As such, the Department is proposing to amend section 40.311(f) to 
clarify that in cases where the report required by section 40.311 is 
provided to an employee with no current employer, the follow-up testing 
plan information (required by section 40.311(d)(9) of that report) must 
be redacted before it is sent to the employee, consistent with section 
40.329(c).
Section 40.355 What limitations apply to the activities of service 
agents?
    Section 40.355(j)(2) states that an MRO may make a determination 
that an employee has refused a drug or alcohol test on the basis of 
adulteration or substitution. However, the Department omitted the 
scenario in which the MRO also makes the refusal to test determination 
when there is not an adequate basis for determining that a medical 
condition has, or with a high degree of probability could have, 
precluded the employee from providing a sufficient amount of specimen 
(See section 40.191(d)(2) and section 40.193(d)(2)(i)). As such the 
Department is proposing to include this ``refusal to test'' scenario to 
section 40.355(j)(2) as another situation in which an MRO makes the 
determination on a refusal to test.

Changes to the HHS Mandatory Guidelines That DOT Is Not Proposing To 
Adopt

    While the Department is proposing to harmonize part 40 with the 
laboratory drug testing standards in the revised HHS Mandatory 
Guidelines as required by OTETA of 1991, which are the core scientific 
laboratory functions necessary for the DOT's program, there are some 
items in the revised HHS Mandatory Guidelines that are not specifically 
related to laboratory drug testing standards that DOT is not proposing 
to adopt. It is important to note the DOT has the discretion concerning 
many other aspects of the regulations governing testing in the 
transportation industries' regulated programs.
    For example, HHS established a requirement in both the UrMG and 
OFMG that MROs must submit semiannual reports to HHS on laboratory-
reported positive specimens

[[Page 42373]]

that were verified negative by the MRO, including the reason for the 
negative verification. Specifically, these reports provide HHS with 
oversight of the MRO reporting practices for such specimens, enhance 
HHS's ability to verify the accuracy of MRO reports, and address areas 
of confusion about the Mandatory Guideline requirements. These 
semiannual reports also provide HHS with a clearer picture of illicit 
drug use by Federal job applicants and employees.
    The DOT's drug testing program already has other mechanisms in 
place to assess MRO compliance, and to gauge illicit drug use by 
applicants and DOT-regulated safety-sensitive employees. For example, 
during inspections, audits,\28\ or both, DOT agency auditors, 
inspectors, or investigators review the MRO drug test verifications and 
reporting practices for compliance with part 40. Also, when required by 
DOT agency regulations, DOT-regulated employers submit their Management 
Information System (MIS) reports (i.e., annual aggregate drug/alcohol 
testing data) to the DOT agency. The DOT agencies use this data to 
assess illicit drug use by employees and applicants and to calculate 
the yearly industry annual drug/alcohol random testing rates. 
Therefore, requiring approximately 2,400 MROs involved in the DOT drug 
testing program to submit semi-annual reports on laboratory-positive/
MRO-verified negative results to DOT would be an undue burden to the 
industry, and an added, unnecessary administrative task for DOT to 
review, analyze, and follow up on each report. For these reasons, the 
Department is not proposing this non-laboratory drug testing 
requirement.
---------------------------------------------------------------------------

    \28\ DOT Agencies inspect/audit DOT-regulated employers and 
their service agents (e.g., MRO, SAP, collectors/BATs) as part of 
the Agency's efforts to ensure employer compliance with Part 40 and 
the respective modal regulations. The inspections/audits are 
conducted at a frequency determined by the DOT Agency.
---------------------------------------------------------------------------

    HHS also revised both the UrMG and OFMG to remove two exceptions 
for collectors reporting a refusal to test for a pre-employment test: 
(1) when an applicant fails to appear for the collection in a 
reasonable time; and (2) when an applicant leaves the collection site 
before the collection process begins. HHS explained that there is no 
justification for altering a refusal to test determination based on 
whether a test is being conducted in the employment, or pre-employment, 
context, and removed the exceptions.\29\ HHS requires all donors to 
arrive at the collection site in a reasonable time (as established by 
the Federal agency employer) and requires all donors to remain at the 
collection site until the collection is complete. When the collector 
reports a refusal to test, the Federal agency takes action consistent 
with applicable agency regulations.
---------------------------------------------------------------------------

    \29\ https://www.govinfo.gov/content/pkg/FR-2022-04-07/pdf/2022-06886.pdf (pg. 20563).
---------------------------------------------------------------------------

    In the August 9, 2001 final rule (66 FR 41944),\30\ DOT clarified 
the application of refusal determinations during pre-employment 
testing. The Department said that an applicant can fail to appear for a 
test for a number of legitimate reasons (e.g., took another job, 
decided they did not want to change their present job, or decided they 
did not want to work for a particular employer). In this type of 
situation, the Department believed--and still does--that it would be 
unfair to impose the consequences of a refusal (e.g., having to 
complete the return-to-duty process or take actions to revoke a 
certification under some DOT agency regulations) on the applicant. 
Similarly, there can be situations in which an applicant could 
legitimately leave a collection site before the test actually commences 
(e.g., there is a long wait for the test and the applicant has another 
obligation). DOT additionally clarified that, for the purposes of this 
provision, the commencement of the pre-employment test means the 
collector or applicant has selected a collection container (See section 
40.191(a)(2) & (3)). Once the collection has commenced, the applicant 
has committed to the process and must complete it. If the applicant 
then leaves before the process is complete, or takes another action 
listed in this section as a refusal, the consequences of a refusal 
attach. However, if the applicant leaves the site before the test 
commences, then the applicant is in the same situation as someone who 
does not appear at all for the pre-employment test. The consequences of 
a refusal do not apply in this situation. For these reasons, which the 
Department believes are still valid today, DOT is not proposing this 
non-laboratory drug testing standard issue.
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    Though HHS did not propose any changes to the MRO training 
requirements, they did receive and respond to comments. Specifically, a 
commenter said there needs to be substantial clarification regarding 
additional MRO training on the annual drug testing panel changes and 
suggested that MROs register with SAMHSA to get updates/announcements 
and acknowledge review of the information received. For oral fluid 
testing, a commenter stated that new and existing MROs should receive 
additional training for oral fluid testing.
    HHS responded, and revised its MRO training requirements to clarify 
that MROs must be trained on any revisions to the drug and biomarker 
testing panels. HHS stated that it relies on the approved MRO 
certification entities to ensure that the MROs certified by their 
organizations meet the HHS Mandatory Guidelines requirements. HHS also 
clarified that, in addition to posting the HHS Medical Review Officer 
Guidance Manual and MRO case studies (urine and oral fluid) on its 
website, it issues notices through the NLCP to the approved MRO 
certification entities for dissemination to their certified MROs.
    DOT believes that its MRO training requirements in section 40.121 
already address both issues. First, DOT requires MROs to be 
knowledgeable of alternative medical explanations for laboratory-
confirmed drug test results (urine and oral fluid), and issues relating 
to substituted specimens. Part 40 also requires the MRO training to 
include instruction on interpreting drug and validity test results. The 
Department addressed the issue of whether MROs need additional training 
for oral fluid testing in our May 2023 rule that permits the use of 
oral fluid testing in the DOT program. Based on public comments 
received, DOT stated that it would not require MROs to undergo 
recertification training, but strongly suggested that MROs seek 
supplemental information about oral fluid testing by the time HHS 
certifies at least two oral fluid drug testing laboratories. The 
Department also stated that it supported the approach of MRO training 
organizations offering oral fluid modules to augment the training of 
MROs who are already current on their training certification 
requirements. Like HHS, DOT relies on the MRO certification 
organizations to ensure MROs meet the DOT training requirements. 
Second, regarding receiving updates/announcements from DOT, the 
Department already has a regulatory requirement in place for MROs to 
subscribe to ODAPC's listserv as a mechanism for MROs to keep current 
on any changes to part 40 and other DOT agency-related information.\31\
---------------------------------------------------------------------------

    \31\ https://www.transportation.gov/odapc/get-odapc/email-updates.
---------------------------------------------------------------------------

    HHS revised both the UrMG and OFMG to clarify that only 
prescription medications can be offered as a legitimate medical 
explanation for a positive drug test. HHS made this clarification given 
its concern, rightfully

[[Page 42374]]

so, that several State laws currently allow a physician to write an 
``authorization'' or ``medical recommendation'' for a Schedule I 
substance, specifically marijuana. However, no Schedule I drug, 
including marijuana, has a currently accepted medical use in the United 
States. Part 40 already requires the MRO to accept only a legally valid 
prescription consistent with the Controlled Substance Act (See section 
40.137(a) & 40.141(b)).

V. Regulatory Analyses and Notices

    Changes to Federal regulations must undergo several analyses. 
First, Executive Order (E.O.) 12866 and E.O. 13563 direct that each 
Federal agency shall propose or adopt a regulation only upon a reasoned 
determination that the benefits of the intended regulation justify its 
costs. Second, the Regulatory Flexibility Act of 1980 (Pub. L. 96-354), 
as codified in 5 U.S.C. 601 et seq., requires agencies to analyze the 
economic impact of regulatory changes on small entities. The Paperwork 
Reduction Act of 1995 (PRA) (44 U.S.C. 3501 et seq.) requires that DOT 
consider the impact of paperwork and other information collection 
burdens imposed on the public and, under the provisions of PRA section 
3507(d), obtain approval from OMB for each collection of information it 
conducts, sponsors, or requires through regulations. Section (a)(5) of 
division H of the Fiscal Year 2005 Omnibus Appropriations Act, Public 
Law 108-447, 118 Stat. 3268 (Dec. 8, 2004), and section 208 of the E-
Government Act of 2002, Public Law 107-347, 116 Stat. 2889 (Dec. 17, 
2002) require DOT to conduct a Privacy Impact Assessment (PIA) of a 
regulation that will affect the privacy of individuals. Finally, the 
National Environmental Policy Act of 1969 (NEPA) (42 U.S.C. 4321 et 
seq.) requires DOT to analyze this action to determine whether it will 
have an effect on the quality of the environment. This portion of the 
preamble summarizes DOT's analyses of these impacts with respect to 
this notice.

E.O. 12866, E.O. 13563, and DOT's Regulatory Policies and Procedures

    This proposed rule is not a significant regulatory action under 
E.O. 12866 and E.O. 13563, as well as under the Department's Regulatory 
Policies and Procedures (49 CFR part 5 and DOT Order 2100.6B). It 
harmonizes specific part 40 procedures with recently revised HHS 
Mandatory Guidelines for urine and oral fluid. The economic impact of 
this rulemaking is discussed in the sections that follow.

E.O. 14192

    OST has reviewed this NPRM for compliance with E.O. 14192 
(``Unleashing Prosperity Through Deregulation''), which requires 
Federal agencies to offset the number and cost of new regulations 
through the repeal, revocation, or revision of existing regulations. As 
discussed above, this action is not a significant rule under E.O. 
12866. Accordingly, this proposed rule is not an E.O. 14192 regulatory 
action because this rule is not significant under E.O. 12866.

Costs

    HHS addressed the cost burdens associated with the addition of a 
new drug to the drug testing panel during the March 5, 2024 DTAB open 
session and its January 16, 2025 Federal Register notice (90 FR 
4662).\32\ According to HHS, HHS-certified test facilities and MROs 
will incur initial costs for administrative and programming changes for 
the addition of fentanyl and norfentanyl.\33\ The cost impact of drug 
testing for fentanyl and norfentanyl would be minimal for those 
laboratories that already offer fentanyl and norfentanyl testing for 
non-DOT testing. Those laboratories that use the same cutoff(s) for 
their non-regulated clients may experience some savings compared to 
laboratories that do not test for these analytes. Because these costs 
would be realized due to participating in the Federal Workplace Drug 
Testing program, the proposed rule will not duplicate this cost.
---------------------------------------------------------------------------

    \33\ SAMHSA DTAB Meeting, March 5, 2024, Transcript, at 44, 
https://www.samhsa.gov/sites/default/files/meeting/transcripts/dtab-meeting-transcript-03052024.pdf.
---------------------------------------------------------------------------

    Once the testing has been implemented, according to HHS, the 
laboratory cost for screening a specimen for the added analytes would 
range from $0.23 to $5.00 due to reagent and administrative costs 
(sample preparation, analysis, and reporting). The cost for each 
confirmatory test would range from $8.00 to $25.00 for each specimen 
due to reagent and administrative costs.\34\ For our analysis, the 
Department will use the average of the low and high values for 
screening ($2.61) and confirmation ($16.5) costs for testing, given 
that the cost will be less based on the volume of tests a laboratory 
conducts and that a majority of the specimens are analyzed by less than 
half of the laboratories conducting the testing. DOT will not consider 
the cost of reviewing negative fentanyl results in this analysis as it 
would be duplicative of costs already incurred for the administrative 
task of reviewing/reporting other negative results for the same 
specimen. Similarly, DOT will not consider specimen collection costs as 
there will not be any additional costs related to the collection of a 
urine specimen, as the urine specimen is already being collected for 
the analysis of the other drugs for which the Department requires 
testing.
---------------------------------------------------------------------------

    \34\ SAMHSA DTAB Meeting, March 5, 2025. Presentation, slide 4.
---------------------------------------------------------------------------

    HHS indicated that based on information from non-regulated 
workplace drug testing for these analytes in 2017, 2019, and 2022 and 
testing performed on de-identified federally regulated specimens in 
2023, approximately 0.19 percent of the submitted specimens are 
expected to be screened as positive for the added analytes and that 84 
percent of those specimens that screen positive will confirm positive. 
Based on this information and the approximate 6.9M annual DOT drug 
tests, DOT estimates 13,110 specimens to screen positive (6.9M x .19%) 
and 11,012 specimens to confirm positive (13,110 x 84%). The estimated 
lab costs for screening tests are $18,009,000 (6.9M x $2.61) and the 
estimated lab costs for confirmation tests are $216,315 (13,110 x 
$16.5).
    Testing for fentanyl will also result in an increased number of 
positive results requiring MRO reviews. Regarding MRO review fees, the 
Department understands that most MROs offer bundled pricing (e.g., one 
fee for reviewing/reporting negative and non-negative results). The 
Department also understands that the fee for a bundled review ranges 
from $8-$18. Using an average of the high and low fee of $13 for our 
analysis, DOT estimates $143,156 in MRO costs (11,102 x $13/MRO review) 
for reviewing laboratory confirmed fentanyl results.
    Therefore, with the estimated 6.9M drug tests conducted annually, 
laboratory and MRO costs, an estimated annual cost of $18,368,471 would 
be realized in the DOT-regulated urine drug testing program.
    Regarding the adjustment to the morphine cutoff from 2,000 ng/mL to 
4,000 ng/ml, DOT estimates that approximately 1,782 of the 6.9 million 
drug tests administered in the DOT program in 2023 were reported with 
morphine results between 2,000 ng/mL and 15,000 ng/mL (899 tests were 
between 2,000-4,000 ng/mL, and 883 tests were between 4,000-15,000 ng/
mL). Based on the current morphine cutoff, with an average clinical 
exam cost of $200 and $13 for the MRO review, DOT estimates the cost 
for the 1,782 clinical exams would be

[[Page 42375]]

approximately $379,566. Given the proposed morphine cutoff, those same 
1,782 test results would now just be MRO reviewed with no clinical exam 
resulting in a cost of $23,166 (1,782 x $13). Therefore, the Department 
estimates a cost savings of approximately $356,400 ($379,566-$23,166).
    At this time, HHS does not require HHS-certified test facilities to 
implement authorized biomarker tests. Each laboratory and IITF should 
conduct its own cost analysis when deciding whether to offer biomarker 
testing to federally regulated clients. HHS will consider costs when 
deciding whether to require all certified test facilities to test for a 
specific biomarker.

Economic Impact

    The estimated cost of adding fentanyl to the drug testing panel and 
adjusting the morphine cutoff level and not requiring a clinical exam 
would be $18,102,071. If identifying illicit drug use by safety-
sensitive transportation employees subjected to drug testing prevents a 
single serious accident, then the benefits of this rule outweigh its 
minimal cost. Testing for fentanyl will add another layer of deterrence 
to illicit drug use. Identifying fentanyl as the drug used by the 
employee will assist SAPs in their assessments and determinations on 
the appropriate recommendations for education or treatment, or both, of 
the employee. This rule would not have a major impact under Executive 
Order 12866 because it would not have an annual effect on the economy 
of $100 million or more, nor would it adversely affect any sector of 
the economy. Because fentanyl is extremely potent, powerful, addictive, 
and dangerous, it is a significant factor in both fatal and nonfatal 
overdoses in the United States, making it a crucial public safety 
issue. Therefore, the Department believes that the benefits of this 
rulemaking outweigh the associated costs.

Regulatory Flexibility Analysis

    The Regulatory Flexibility Act of 1980 (5 U.S.C. 601 et seq.) 
requires Federal agencies to consider the effects of their regulatory 
actions on small businesses and other small entities and minimize any 
significant economic impact. The term ``small entities'' comprises 
small businesses and not-for-profit organizations that are 
independently owned and operated and are not dominant in their fields, 
and governmental jurisdictions with a population of less than 50,000.
    The Department does not expect that the proposed rule would have a 
significant economic impact on a substantial number of small entities. 
Many thousands of covered employers are small businesses (e.g., small 
trucking companies, small transit authorities), as are many service 
agents (e.g., drug testing laboratories, medical review officers), but 
given the small net change in regulatory costs spread over these 
thousands of small entities, the cost impact per entity is expected to 
be negligible. Our ability to create special provisions for small 
entities is limited by the need to have uniform requirements to ensure 
safety and fairness to employees. There must be a single standard for 
the accuracy and integrity of the program and the protection of 
legitimate employee interests that cannot vary with the size of the 
employer or service agent.
    The proposed rule, if adopted, would modify certain part 40 
procedures and is intended only to further align our laboratory 
procedures and processes and MRO procedures, with those requirements 
that are being directed by the HHS Guidelines, which were considered 
nonsignificant. The Department would note that all HHS-certified 
laboratories must have the capability to accurately test for fentanyl 
and norfentanyl to pass certification requirements of the National 
Laboratory Certification Program. In addition, Federal agency employee 
testing programs are already testing for fentanyl and norfentanyl and 
MROs are no longer required to conduct clinical evaluations to 
determine illicit opioid use. Our harmonizing on these matters will 
only bring clarity and consistency to the efforts of the Federal 
testing programs, programs that are internal to the Federal Government, 
and those that are regulated by the Federal Government.

Federalism

    E.O. 13132 requires Federal agencies to carefully examine actions 
to determine if they contain policies that have federalism implications 
or that preempt State law. As defined in the order, ``policies that 
have federalism implications'' refer to regulations, legislative 
comments or proposed legislation, and other policy statements or 
actions that have substantial direct effects on the States, on the 
relationship between the National Government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.
    Most of the regulated parties under the Department's drug testing 
program are private entities. Some regulated entities are public 
entities (e.g., transit authorities and public works departments); 
however, the Secretary has determined that the proposed rule, which, if 
adopted, would require the testing of safety-sensitive employees in the 
transportation industry for fentanyl and norfentanyl, remove the 
requirement for MROs to look for clinical evidence of illicit opiate 
use, and authorize the use of biomarker testing to determine if a 
specimen was substituted does not contain policies that have federalism 
implications.

Paperwork Reduction Act

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3501-3520) (PRA) 
requires that DOT consider the impact of paperwork and other 
information collection burdens imposed on the public. This proposed 
rule would not require any new collection of information under the PRA. 
Notwithstanding any other provision of law, no person shall be subject 
to any penalty for failing to comply with a collection of information 
subject to the PRA that does not display a currently valid Office of 
Management and Budget (OMB) control number. Information collections for 
part 40 currently are approved under OMB Control No. 2105-0529. This 
proposed rule will not create any new paperwork or other information 
collection burdens that require approval.

Privacy Act

    The Privacy Act provides safeguards against invasion of personal 
privacy through the misuse of records by Federal agencies. It 
establishes controls over what personal information is collected, 
maintained, used, and disseminated by agencies in the executive branch 
of the Federal Government. Anyone is able to search the electronic form 
of all comments received in any of our dockets by the name of the 
individual submitting the comment (or signing the comment, if submitted 
on behalf of an association, business, labor union, etc.). For 
information on DOT's compliance with the Privacy Act, please visit 
https://www.transportation.gov/privacy.

National Environmental Policy Act

    The Department has analyzed the environmental impacts of this 
notice of proposed rulemaking pursuant to NEPA (42 U.S.C. 4321 et 
seq.). The Department has determined that this rule is categorically 
excluded pursuant to 23 CFR 771.118(c)(4). Categorical exclusions are 
categories of actions that the agency has determined normally do not 
significantly affect the quality of the human environment and therefore 
do not require either an environmental

[[Page 42376]]

assessment (EA) or environmental impact statement (EIS). See DOT Order 
5610.1D Sec.  9. In analyzing the applicability of a categorical 
exclusion, the agency must also consider whether extraordinary 
circumstances are present that would warrant the preparation of an EA 
or EIS. Id. Sec.  9(b). The Department's Operating Administrations 
(OAs) may apply CEs established in another OA's procedures. Id. Sec.  
9(f). To do so, the Operating Administration ``must evaluate the action 
for extraordinary circumstances identified in the OA procedures in 
which the CE is established to determine if a normally excluded action 
may have a significant impact and coordinate with the originating OA to 
ensure that the CE is being applied correctly.'' Id. This rulemaking, 
which proposes to amend its drug-testing program regulation, 49 CFR 
part 40 (part 40), to add fentanyl and norfentanyl to its drug testing 
program, to amend certain provisions of part 40 to harmonize, as 
appropriate, with the recently revised HHS Mandatory Guidelines using 
urine and oral fluid, and to make technical amendments, is 
categorically excluded pursuant to 23 CFR 771.118(c)(4): ``Planning and 
administrative activities not involving or leading directly to 
construction, such as: Training, technical assistance and research; 
promulgation of rules, regulations, directives, or program guidance; 
approval of project concepts; engineering; and operating assistance to 
transit authorities to continue existing service or increase service to 
meet routine demand.'' The Department has coordinated with the Federal 
Transit Administration to ensure that this CE is being applied 
correctly. The Department does not anticipate any environmental 
impacts, and there are no extraordinary circumstances present in 
connection with this rulemaking.

Unfunded Mandates Reform Act

    The Secretary has examined the impact of this proposed rule under 
the Unfunded Mandates Reform Act (UMRA) of 1995 (Pub. L. 104-4). This 
proposed rule does not trigger the requirement for a written statement 
under sec. 202(a) of the UMRA because this rulemaking does not impose a 
mandate that results in an expenditure of $100 million or more by 
either State, local, and Tribal governments in the aggregate or by the 
private sector in any one year.

8. In Sec.  40.35, revise subparagraph (c)(1), and paragraphs (d) and 
(f) to read:


Sec.  40.35  What training requirements must a collector meet for oral 
fluid collection?

* * * * *
    (c)(1) The five mock collections for each device must include one 
uneventful collection scenario; one insufficient specimen quantity 
scenario; one scenario in which the employee has something in their 
mouth that might interfere with the collection; one scenario in which 
the employee attempts to tamper with the specimen; and one scenario in 
which the employee refuses to sign the CCF and initial the specimen 
bottle tamper-evident seal. For each of the five mock collections, the 
collector must check the expiration date of the device, show the 
expiration date to the employee, and record the date on the CCF used. 
The collector must ensure that when applying the labels, they do not 
cover the expiration dates.
* * * * *
    (d) Schedule for qualification training and initial proficiency 
demonstration. You must meet the requirements of paragraphs (b) and (c) 
of this section within 30 days of completing the qualification 
training. If you do not complete the initial proficiency demonstration 
within 30 days of successfully completing the qualification training, 
you must again complete the qualification training.
* * * * *
    (f) Error Correction Training. If you make a mistake in the 
collection process that causes a test to be cancelled (i.e., a fatal or 
uncorrected flaw), you must undergo error correction training. This 
training must occur within 30 days of the date you are notified of the 
error that led to the need for retraining. If a cancellation is due to 
an error that occurs outside the collection process (e.g., when a 
specimen is crushed or otherwise damaged during the transportation 
process, or is lost in transit), the cancellation is not the result of 
an error by the collector during the collection process and does not 
require the collector to be retrained.

    (f) Direct the employee to remove outer clothing (e.g., coveralls, 
jacket, coat, hat) that could be used to conceal items or substances 
that could be used to tamper with a specimen. You must also direct the 
employee to leave these garments and any briefcase, purse, or other 
personal belongings with you or in a mutually agreeable location. If 
the employee refuses, the collector must terminate the collection, note 
the circumstances in the Remarks section of the CCF, and report the 
information to the DER as described in Sec.  40.191(a)(8) (failure to 
cooperate), so that the employer can decide whether to deem the 
situation a refusal.

    (i) Document any unusual characteristics referenced above in the 
Remarks section of the CCF and complete the collection.
    (ii) Proceed with obtaining the new oral fluid specimen from the 
donor. You must process both the original specimen and the newly 
collected specimen and send the two sets of specimens to the 
laboratory. Note on the new CCF that this is another collection for the 
same testing event (e.g., document in the Remarks section that this is 
Specimen 2 of 2 and include the Specimen ID number of the other 
specimen). Make the same notation on the CCF of the suspect specimen 
but note that it is Specimen 1 of 2.
    (iii) If the employee refuses to provide another specimen, you must 
discard any specimen the employee provided previously during the 
collection procedure. Note the circumstances in the Remarks section of 
the CCF and report the information to the DER as described in 
40.191(a)(8) (failure to cooperate), so that the employer can determine 
whether to deem the situation a refusal.

\1\ For grouped analytes (i.e., two or more analytes that are in the same drug class and have the same initial
  test cutoff):
Immunoassay: The test must be calibrated with one analyte from the group identified as the target analyte. The
  cross-reactivity of the immunoassay to the other analyte(s) within the group must be 80 percent or greater; if
  not, separate immunoassays must be used for the analytes within the group.
Alternate technology: Either one analyte or all analytes from the group must be used for calibration, depending
  on the technology. For a technology that measures a response from the entire group without differentiating
  between analytes (e.g., an activity-based assay, a mass spectrometric assay that does not differentiate
  isobaric compounds), the laboratory must compare the result to the initial test cutoff. In the case of an
  alternate technology that differentiates and quantifies each analyte in the group, the laboratory must compare
  each analyte's result to the confirmatory test cutoff and reflex specimens with a positive initial test result
  to confirmatory testing.
\2\Alternate technology (BZE): The confirmatory test cutoff must be used for an alternate technology initial
  test that is specific for the target analyte (i.e., 100 ng/mL for benzoylecgonine).
\3\A fentanyl immunoassay must have at least 5% cross-reactivity to norfentanyl.

\1\ For grouped analytes (i.e., two or more analytes that are in the same drug class and have the same initial
  test cutoff):

[[Page 42379]]

 
Immunoassay: The test must be calibrated with one analyte from the group identified as the target analyte. The
  cross-reactivity of the immunoassay to the other analyte(s) within the group must be 80 percent or greater; if
  not, separate immunoassays must be used for the analytes within the group.
Alternate technology: Either one analyte or all analytes from the group must be used for calibration, depending
  on the technology. For a technology that measures a response from the entire group without differentiating
  between analytes (e.g., an activity-based assay, a mass spectrometric assay that does not differentiate
  isobaric compounds), the laboratory must compare the result to the initial test cutoff. In the case of an
  alternate technology that differentiates and quantifies each analyte in the group, the laboratory must compare
  each analyte's result to the confirmatory test cutoff and reflex specimens with a positive initial test result
  to confirmatory testing.
\2\Alternate technology (6-AM): The confirmatory test cutoff must be used for an alternate technology initial
  test that is specific for the target analyte (i.e., 2 ng/mL for 6-AM).

19. Revise Sec.  40.92 by adding a new paragraph (d), redesignating 
paragraph (c) as paragraph (d) and revising paragraph (c) to read as 
follows:


Sec.  40.92  What is oral fluid validity testing, and are laboratories 
required to conduct it?

* * * * *
    (c) You may perform initial and confirmation biomarker testing as 
authorized by the HHS Mandatory Guidelines for oral fluid.
* * * * *

20. Revise Sec.  40.93 to read as follows:


Sec.  40.93  What validity tests must laboratories conduct on primary 
oral fluid specimens?

    As a laboratory, if you conduct validity testing under Sec.  40.92, 
you must conduct it in accordance with the applicable HHS Mandatory 
Guidelines requirements for validity testing or biomarker testing, or 
both.
0
21. Create a new Sec.  40.95 to read as follows:


Sec.  40.95  What criteria do laboratories use to establish that an 
oral fluid specimen is substituted?

    As a laboratory, you must consider the primary specimen to be 
substituted when a biomarker is not detected or is present at a 
concentration inconsistent with that established for a human oral fluid 
for both the initial test and the confirmatory test on two separate 
aliquots (i.e., using the test analytes and cutoffs listed in the HHS 
biomarker testing panel).

22. Amend Sec.  40.137 by revising paragraphs (a) and (c) to read as 
follows:


Sec.  40.137  On what basis does the MRO verify test results involving 
marijuana, cocaine, amphetamines, opioids, or PCP?

    (a) As the MRO, you must verify a confirmed positive test result 
for one or more of either marijuana, cocaine, amphetamines, opioids, or 
PCP, unless the employee presents a legitimate medical explanation for 
the presence of the drug(s)/metabolite(s) in his or her system. In 
determining whether an employee's legally valid prescription consistent 
with the Controlled Substances Act for a substance in these categories 
constitutes a legitimate medical explanation, you must not question 
whether the prescribing physician should have prescribed the substance.
* * * * *
    (c)(1) The employee has the burden of proof that a legitimate 
medical explanation exists. The employee must present information 
meeting this burden at the time of the verification interview. As the 
MRO, you have discretion to extend the time available to the employee 
for this purpose for up to five days before verifying the test result, 
if you determine that there is a reasonable basis to believe that the 
employee will be able to produce relevant evidence concerning a 
legitimate medical explanation within that time.
    (2) If the laboratory confirms the presence of 6-acetylmorphine (6-
AM) in the specimen, you must verify the test result as positive.
    (3) When verifying codeine or morphine results in urine, 
consumption of food products (e.g., poppy seeds) must not be considered 
a legitimate medical explanation for the employee having morphine or 
codeine results above the confirmatory cutoffs listed in Sec.  40.85.
    (4) When verifying codeine or morphine results in oral fluid, you 
must verify a result between 15 ng/mL and 150 ng/mL as ``negative'' 
when the employee claims ingestion of poppy seed products, unless the 
employee admits to unauthorized use.
    (5) For all other results, you must verify the result as `positive' 
unless the employee presents a legitimate medical explanation for the 
presence of the drug/metabolite in his or her system.

Sec.  40.141  How does the MRO obtain information for the verification 
decision?

* * * * *
    (b) * * *
    (2) When verifying lab results, you may, as you deem necessary, 
request that an HHS-certified laboratory with validated protocols (see 
Sec.  40.81(c)) to conduct testing for D,L stereoisomers of amphetamine 
and methamphetamine (for either urine or oral fluid specimens) or for 
tetrahydrocannabivarin (THC-V) (for urine only).
0
25. Revise Sec.  40.145 (d), (e)(2), and (h) to read as follows:


Sec.  40.145  On what basis does the MRO verify test results involving 
adulteration or substitution?

* * * * *
    (d) You must offer the employee the opportunity to present a 
legitimate medical explanation for the laboratory findings with respect 
to the presence of the adulterant in the specimen, the creatinine and 
specific gravity findings for the urine specimen, or the absence of a 
biomarker or a biomarker concentration that is not consistent with that 
established for human urine or oral fluid.
* * * * *
    (e) * * *
    (2) To meet this burden in the case of a substituted specimen, the 
employee must demonstrate that he or she did produce or could have 
produced a specimen through physiological means, for urine, meeting the 
creatinine concentration criterion of less than 2 mg/dL and the 
specific gravity of less than or equal to 1.0010 or greater than or 
equal to 1.0200 (see Sec.  40.88(b)), or for urine or oral fluid, 
absent a biomarker or with a biomarker concentration that is not 
consistent with that established for human urine or oral fluid..
* * * * *
    (h) The following are examples of types of evidence an employee 
could present to support an assertion of a legitimate medical 
explanation for a substituted result.
    (1) Medically valid evidence demonstrating that the employee is 
capable of physiologically producing urine meeting the creatinine and 
specific gravity criteria of Sec.  40.88(b) or producing a specimen 
absent a biomarker or with a biomarker concentration that is not 
consistent with that established for human urine or fluid.
    (i) To be regarded as medically valid, the evidence must have been 
gathered using appropriate methodology and controls to ensure its 
accuracy and reliability.
    (ii) Assertion by the employee that his or her personal 
characteristics (e.g., with respect to race, gender, weight, diet, or 
working conditions) are responsible for

[[Page 42380]]

the substituted result does not, in itself, constitute a legitimate 
medical explanation. To make a case that there is a legitimate medical 
explanation, the employee must present evidence showing that the cited 
personal characteristics actually result in the physiological 
production of urine meeting the creatinine and specific gravity 
criteria of Sec.  40.88(b) or of a specimen absent a biomarker or with 
a biomarker concentration that is not consistent with that established 
for human urine or fluid.
    (2) Information from a medical evaluation under paragraph (g) of 
this section that the individual has a medical condition that has been 
demonstrated to cause the employee to physiologically produce urine 
meeting the creatinine and specific gravity criteria of Sec.  40.93(b), 
or physiologically producing a specimen absent a biomarker or with a 
biomarker concentration that is not consistent with that established 
for human urine or fluid.
    (i) A finding or diagnosis by the physician that an employee has a 
medical condition does not in itself constitute a legitimate medical 
explanation.
    (ii) To establish there is a legitimate medical explanation, the 
employee must demonstrate that the cited medical condition actually 
results in the physiological production of urine meeting the creatinine 
and specific gravity criteria of Sec.  40.88(b) or of a specimen absent 
a biomarker or with a biomarker concentration that is not consistent 
with that established for human urine or fluid.

26. Revise Sec.  40.151(d) to read as follows:


Sec.  40.151  What are MROs prohibited from doing as part of the 
verification process?

* * * * *
    (d) It is not your function to consider explanations of confirmed 
positive, adulterated, or substituted test results that would not, even 
if true, constitute a legitimate medical explanation. For example, an 
employee may tell you that someone slipped amphetamines into her drink 
at a party, that she unknowingly ingested a marijuana brownie, or that 
she traveled in a closed car with several people smoking crack. MROs 
are unlikely to be able to verify the facts of such passive or 
unknowing ingestion stories. Even if true, such stories do not present 
a legitimate medical explanation. Consequently, for all drugs except 
codeine/morphine oral fluid results as described in Sec.  40.137(c)(4), 
you must not declare a test as negative based on an explanation of this 
kind.
* * * * *

27. Revise 40.181 to read:


Sec.  40.181  What does the second laboratory do with the split 
specimen when it is tested to reconfirm a substituted test result?

    (a) As the laboratory testing a urine split specimen, you must test 
the split specimen using the confirmatory tests for creatinine and 
specific gravity, using the criteria set forth in Sec.  40.88.
    (b) As the laboratory testing a urine split specimen reported as 
substituted based on biomarker testing, you must test for the biomarker 
using its confirmatory test (i.e., using the confirmatory test analytes 
and cutoffs in the HHS biomarker testing panel)
    (c) As the laboratory testing an oral fluid split specimen, you 
must only conduct the confirmatory biomarker test(s) needed to 
reconfirm the substituted results reported by the first HHS-certified 
laboratory.

28. In Sec.  40.193, revise paragraph (a) introductory text and 
paragraph (b)(2) to read:


Sec.  40.193  What happens when an employee does not provide a 
sufficient amount of specimen for a drug test?

    (a) If an employee does not provide a sufficient amount of specimen 
to permit a drug test (i.e., 45 mL of urine in a single void, or 2 mL 
oral fluid in a single sampling, as applicable) you, as the collector, 
must provide another opportunity to the employee to do so. In 
accordance with the employer's instructions or standing orders, this 
can be done using the same specimen type as the original collection or 
this can be done by a collector qualified to use an alternate specimen 
type for this purpose.
* * * * *
    (b) * * *
    (2) As the collector, you must do the following when continuing 
with an oral fluid specimen collection under this section:
    (i) Discard the insufficient specimen except where the insufficient 
specimen showed unusual characteristics (see Sec.  40.73(c)(4)).
    (ii) If the employee demonstrates an inability to provide a 
specimen in accordance with the manufacturer's instructions for using 
the collection device, and if the donor states that he or she could 
provide a specimen after drinking some fluids, urge the employee to 
drink (up to 8 ounces) and wait an additional 10 minutes before 
beginning the next specimen collection (a period of up to one hour must 
be provided, or until the donor has provided a sufficient oral fluid 
specimen, whichever occurs first). If the employee simply needs more 
time before attempting to provide an oral fluid specimen, the employee 
is not required to drink any fluids during the one-hour wait time. It 
is not a refusal to test if the employee declines to drink. The 
employee must remain at the collection site, in a monitored area 
designated by the collector, during the wait period.
    (iii) If the employee refuses to attempt to provide a new oral 
fluid specimen or leaves the collection site before the collection 
process is complete, you must discontinue the collection, note that 
fact on the ``Remarks'' line of the CCF (Step 2), and immediately 
notify the DER of the conduct as provided in Sec.  40.191(e)(1); the 
employer decides whether the situation is deemed to be a refusal.
    (iv) If the employee has not provided a sufficient specimen within 
one hour of the first unsuccessful attempt to provide the specimen, you 
must discontinue the collection, note the fact on the ``Remarks'' line 
of the CCF (Step 2), and immediately notify the DER. You must also 
discard any specimen the employee previously provided, including any 
specimen that shows any unusual characteristics or signs of tampering. 
In the Remarks section of the CCF that you will distribute to the MRO 
and DER, note the fact that the employee provided a ``specimen that 
shows unusual characteristics or signs of tampering'' and that it was 
discarded because the employee did not provide a sufficient specimen.

29. Revise Sec.  40.199 by adding a new (b)(10) to read as follows:


Sec.  40.199  What problems always cause a drug test to be cancelled?

* * * * *
    (b) * * *
    (10) For an oral fluid collection, the collector failed to document 
the observation of the volume indicator(s) at the time of the 
collection for a collection device containing a diluent.

30. In Sec.  40.213, revise paragraph (d) to read:


Sec.  40.213  What training requirements must STTs and BATs meet?

* * * * *
    (d) Schedule for qualification training and initial proficiency 
demonstration. You must meet the requirements of paragraphs (b) and (c) 
of this section within 30 days of completing the qualification 
training. If you do not complete the initial proficiency demonstration 
within 30 days of

[[Page 42381]]

successfully completing the qualification training, you must again 
complete the qualification training.

31. In Sec.  40.311, revise paragraph (f) to read:


Sec.  40.311  What are the requirements concerning SAP reports?

* * * * *
    (f) As a SAP, you must also provide these written reports directly 
to the employee if the employee has no current employer and to the 
gaining DOT regulated employer in the event the employee obtains 
another transportation industry safety-sensitive position. When 
providing the reports to the employee, you must redact the follow up 
testing plan information (see Sec.  40.329(c)).

    (j) * * *
    (2) As an MRO, you determine that an individual has refused to test 
on the basis of adulteration, substitution, or there is not an adequate 
basis for determining that a medical condition has, or with a high 
degree of probability could have, precluded the employee from providing 
a sufficient amount of specimen.
