Federal Plan Requirements for Hospital/Medical/Infectious Waste 
Incinerators Constructed On or Before June 20, 1996

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: On September 15, 1997, EPA adopted emission guidelines for 
existing hospital/medical/infectious waste incinerator(s) (HMIWI). 
Sections 111 and 129 of the Clean Air Act (Act or CAA) require States 
with existing HMIWI subject to the emission guidelines to submit plans 
to EPA that implement and enforce the emission guidelines. Indian 
tribes may submit, but are not required to submit, Tribal plans to 
implement and enforce the emission guidelines in Indian country. State 
plans were due from States with HMIWI subject to the emission 
guidelines on September 15, 1998. If a State or Tribe with existing 
HMIWI does not submit an approvable plan within 2 years after 
promulgation of the emission guidelines (September 15, 1999), sections 
111(d) and 129 of the Act require EPA to develop, implement, and 
enforce a Federal plan for HMIWI in that State/Tribal area. In this 
action the EPA proposes a Federal plan to implement emission guidelines 
for HMIWI located in States and Indian country without effective State 
or Tribal plans. This Federal plan will most likely be an interim 
action for many of these areas because when a State/Tribal plan becomes 
effective, the Federal plan will no longer apply to HMIWI covered by 
such plan.

I. Background

A. HMIWI Regulations

    On September 15, 1997, EPA promulgated emission guidelines for 
existing HMIWI under authority of sections 111 and 129 of the Act. See 
62 FR 48348 (to be codified at 40 CFR part 60, subpart Ce, Secs. 60.30e 
through 60.39e). To make these emission guidelines enforceable, States 
with existing HMIWI were required to submit to EPA within 1 year 
following promulgation of the emission guidelines a State plan that 
implements and enforces the emission guidelines. States without any 
existing HMIWI were required to submit to the Administrator a letter of 
negative declaration certifying that there are no HMIWI in the State. 
No plan is required for States that do not have any HMIWI.
    As discussed in section I.D. of this preamble, Indian Tribes may, 
but are not required to, submit Tribal plans to cover HMIWI in Indian 
country. A Tribe may submit to the Administrator a letter of negative 
declaration certifying that no HMIWI are located in the Tribal area. No 
plan is required for Tribes that do not have any HMIWI.
    Sections 111 and 129 of the Act and 40 CFR 60.27(c) and (d) require 
EPA to develop, implement, and enforce a Federal plan to cover existing 
HMIWI located in States that do not have an approved plan. Furthermore, 
EPA plans to develop, implement, and enforce a Federal plan for Indian 
country until Tribes receive approval to administer their own programs. 
Hospital/medical/infectious waste incinerators located in States or 
Tribal areas that mistakenly submit a letter of negative declaration 
would be subject to the Federal plan until a State or Tribal plan that 
includes these HMIWI is approved and effective. Today's action proposes 
the HMIWI Federal plan.

B. Who This HMIWI Federal Plan Affects

    This proposed HMIWI Federal plan would affect existing HMIWI for 
which construction commenced on or before June 20, 1996. HMIWIs would 
be subject to this Federal plan if any of the following is true on the 
effective date of the Federal plan:

[[Page 36428]]

    (1) The State or Tribal plan has not become effective;a
---------------------------------------------------------------------------

    \a\ The effective date of a State or Tribal plan from EPA's 
perspective (a State and Tribe may have an earlier effective date) 
is 30 days after the State or Tribal plan approval is published in 
the Federal Register if the approval is via the regular regulatory 
procedure of proposal with opportunity for comment followed by 
promulgation. If the approval is by direct final rule making, the 
effective date of the State/Tribal plan is 60 days after the 
approval is published in the Federal Register if no adverse comments 
are received.
---------------------------------------------------------------------------

    (2) The State or Tribal plan was in effect but was subsequently 
vacated in whole or in part; or
    (3) The State or Tribal plan was in effect but was subsequently 
revised such that it is no longer as protective as the emission 
guidelines.
    The specific applicability of this plan is described in proposed 
Secs. 62.14400 through 62.14403 of subpart HHH.
    The Federal plan would become effective 30 days after final 
promulgation. Once an approved State or Tribal plan is in effect, the 
Federal plan would no longer apply to HMIWI covered by such plan.

C. Implementing Authority

    The EPA Regional Administrators will be the delegated authority for 
implementing the HMIWI Federal plan. All reports required by this 
Federal plan should be submitted to the appropriate Regional Office 
Administrator. Table 2 under SUPPLEMENTARY INFORMATION lists the names 
and addresses of the EPA Regional Office contacts and the States that 
they cover.

D. HMIWI Federal Plan and Indian Country

    The term ``Indian country,'' as used in this preamble, means (1) 
all land within the limits of any Indian reservation under the 
jurisdiction of the United States government, notwithstanding the 
issuance of any patent, and including rights-of-way running through the 
reservation; (2) all dependent Indian communities within the borders of 
the United States whether within the original or subsequently acquired 
territory thereof, and whether within or without the limits of a State; 
and (3) all Indian allotments, the Indian titles to which have not been 
extinguished, including rights-of-way running through the same.
    The HMIWI Federal plan would apply throughout Indian country to 
ensure that there is not a regulatory gap for existing HMIWI in Indian 
country. However, Indian tribes now have the authority under the Act to 
develop Tribal plans in the same manner that States develop State 
plans. On February 12, 1998, EPA promulgated regulations that outline 
provisions of the Act for which EPA is authorized to treat Tribes in 
the same manner as States. See 63 FR 7254 (Final Rule for Indian 
Tribes: Air Quality Planning and Management, (Tribal Authority Rule)) 
(codified at 40 CFR part 49). As of March 16, 1998, the effective date 
of the Tribal Authority Rule, EPA has had authority under the Act to 
approve Tribal programs such as Tribal plans to implement and enforce 
HMIWI emission guidelines.
1. Tribal Implementation
    Section 301(d) of the Act authorizes the Administrator to treat an 
Indian tribe as a State under certain circumstances. The Tribal 
Authority Rule, which implements section 301(d) of the Act, identifies 
provisions of the Act for which a Tribe should be treated as a State. 
See 40 CFR 49.3 and 49.4. Under the Tribal Authority Rule, a Tribe is 
treated as a State for purposes of this Federal plan. If a Tribe meets 
the criteria below, EPA can delegate to an Indian tribe authority to 
implement the Federal plan in the same way it can delegate authority to 
a State:
    (1) The applicant is an Indian tribe recognized by the Secretary of 
the Interior;
    (2) The Indian tribe has a governing body carrying out substantial 
governmental duties and functions;
    (3) The functions to be exercised by the Indian tribe pertain to 
the management and protection of air resources within the exterior 
boundaries of the reservation or other areas within the tribe's 
jurisdiction; and
    (4) The Indian tribe is reasonably expected to be capable, in the 
EPA Regional Administrator's judgement, of carrying out the functions 
to be exercised in a manner consistent with the terms and purposes of 
the Act and all applicable regulations. See 40 CFR 49.6.
2. EPA Implementation
    The Act also provides EPA with the authority to administer Federal 
programs in Indian country. This authority is based in part on the 
general purpose of the Act, which is national in scope. Section 301(a) 
of the Act provides EPA broad authority to issue regulations that are 
necessary to carry out the functions of the Act. The EPA believes that 
Congress intended for EPA to have the authority to operate a Federal 
program when Tribes choose not to develop a program, do not adopt an 
approvable program, or fail to adequately implement an air program 
authorized under section 301(d) of the Act.
    Section 301(d)(4) of the Act authorizes the Administrator to 
directly administer provisions of the Act to achieve the appropriate 
purpose where Tribal implementation is not appropriate or 
administratively not feasible. The Agency's interpretation of its 
authority to directly implement Clean Air Act programs in Indian 
country is discussed in more detail in the proposed Federal Operating 
Permits Rule, see 62 FR 13747 (March 21, 1997), and in the Tribal 
Authority Rule. See 63 FR at 7262-7263.
    Many Tribes may have delayed development of air quality regulations 
and programs pending promulgation of the Tribal Authority Rule. As 
mentioned previously, Tribes may, but are not required to, submit an 
HMIWI plan under section 111(d) of the Act.
3. Applicability in Indian Country
    The Federal plan would apply throughout Indian country except where 
a State or Tribal plan has been explicitly approved by EPA to cover an 
area of Indian country. This approach is consistent with that in the 
proposed Federal Operating Permits Rule cited above where the rationale 
is discussed in detail. The EPA requests comments on applying the HMIWI 
Federal plan in Indian country as described here.

E. HMIWI Federal Plan and Compliance Schedules

    The emission guidelines require the HMIWI owner or operator to come 
into compliance with the State or Tribal plan within 1 year after 
approval of such plan, or within 1 year after promulgation of the 
Federal plan (whichever applies). See 40 CFR 60.39e(b). However, if the 
State or Tribal plan contains measurable and enforceable increments of 
progress, the HMIWI may be allowed up to 3 years after approval of the 
plan (but in no case later than September 15, 2002) to come into 
compliance. See 40 CFR 60.39e(c).
    This proposed Federal plan contains measurable and enforceable 
increments of progress that allow sources up to 3 years after 
promulgation of the Federal plan to comply (but in no case later than 
September 15, 2002.) The increments of progress are discussed in 
section II.E of this preamble.
1. Due Within 1 Year of Promulgation
    Except under the special circumstances that are discussed below, 
HMIWI that are planning to shut down rather than comply with the 
requirements of the Federal plan must do so by the date 1 year after 
the Federal plan is promulgated. In addition, according to 
Sec. 60.39e(e) of subpart Ce, all HMIWI that continue to operate 1 year 
after the Federal plan promulgation date must comply with the operator

[[Page 36429]]

training and qualification requirements and the inspection requirements 
of the plan within 1 year. This includes HMIWI that comply within 1 
year, as well as those that have been granted an extension beyond the 1 
year compliance date (i.e., HMIWI with extended retrofit schedules and 
HMIWI granted an extension pursuant to Sec. 60.39e(d) of subpart Ce).
2. Special Provisions of Sec. 60.39e(d)
    The Federal plan may contain provisions allowing HMIWI that are 
planning to shut down the opportunity to petition the State, Tribe, or 
EPA for an extension beyond the 1-year compliance date. See 40 CFR 
60.39e(d). This proposed Federal plan contains provisions for granting 
and denying petitions for an extension beyond the 1-year compliance 
deadline (but no later than September 15, 2002). An example of a 
facility that might petition the enforcement authority for such an 
extension is a facility installing an onsite alternative waste 
treatment technology. It is possible that installation cannot be 
completed within 1 year, and the facility has no feasible waste 
disposal options other than onsite incineration while the alternative 
technology is being installed.
    The requirements for a petition under the Federal plan, which are 
set forth at proposed Sec. 62.14471 of subpart HHH, are the same as the 
requirements listed at Sec. 60.39e(d) of subpart Ce, except that EPA 
proposes a specific date of 90 days following promulgation of the 
Federal plan by which petitions must be submitted to EPA under the 
Federal plan. This time frame, which is more than 2 years after 
promulgation of the emission guidelines and more than 9 months from 
today's proposal, should give sources sufficient time to examine their 
waste disposal options and to prepare the necessary documentation to 
justify their need for an extension. This time frame also gives EPA 
sufficient time to grant or deny the petition before the 1-year 
compliance deadline arrives.

F. Status of State Plan Submittals

    Sections 111(d) and 129(b)(2) of the Act, as amended, 42 U.S.C. 
7411(d) and 7429(b)(2), authorize EPA to develop and implement a 
Federal plan for HMIWI located in States with no approved and effective 
State plan. The EPA has received final State plans from New York, 
Delaware, Louisiana, Georgia, Alabama, North Dakota, Montana, and 
Colorado. The EPA has received draft State plans from Puerto Rico, 
Maryland, West Virginia, Pennsylvania, Iowa, Ohio, Indiana, Minnesota, 
Illinois, Michigan, South Dakota, Utah, Washington, and Wyoming. Other 
States are making significant progress on their State plans and EPA 
expects many State plans to be approved before this Federal plan is 
final.
    The EPA anticipates letters of negative declaration from New Mexico 
and Oregon. The EPA is not aware of any Indian tribes that are 
developing Tribal plans.
    The preamble of the final Federal plan will list States and Tribes 
that have an EPA-approved plan in effect on the date the final Federal 
plan is signed by the EPA Administrator. As Regional Offices approve 
State plans, they will also, in the same action, amend the appropriate 
subpart of 40 CFR part 62 to codify their approvals.
    The EPA will maintain a list of State plan submittals and approvals 
on the Unified Air Toxics Website at http://www.epa.gov/ttn/uatw/129/
hmiwi/rihmiwi.html. The list will help HMIWI owners or operators 
determine whether their HMIWI is affected by a State plan, a Tribal 
plan, or the Federal plan. Hospital/medical/infectious waste 
incinerator owners and operators can also contact the EPA Regional 
Office for the State in which their HMIWI is located to determine 
whether there is an approved and effective State plan in place.

II. Required Elements of the HMIWI Federal Plan

    Because the EPA is proposing a Federal plan to cover HMIWI located 
in States or Tribes where plans are not in effect, this proposal 
includes the same elements as are required for State plans: (1) 
Identification of legal authority and mechanisms for implementation; 
(2) inventory of HMIWI; (3) emissions inventory; (4) emission limits; 
(5) compliance schedules; (6) public hearing; (7) testing, monitoring, 
inspection, reporting, and recordkeeping; (8) waste management plan; 
(9) operator training and qualification; and (10) progress reporting. 
See 40 CFR part 60 subparts B and C and sections 111 and 129 of the 
Act. Docket item II-B-3 in docket A-98-24 identifies each element and 
indicates where it is addressed. Each element is described below as it 
relates to the proposed HMIWI Federal plan.

A. Legal Authority and Enforcement Mechanism

    A State or Tribal plan must demonstrate that the State or Tribe has 
the legal authority to adopt and implement the emission guidelines. 40 
CFR 60.26. In its plan, the State or Tribe must identify the 
enforcement mechanism for implementing the emission guidelines, such as 
a State or Tribal rule.
1. EPA's Legal Authority in States
    Section 301(a) of the Act provides the EPA with broad authority to 
write regulations that carry out the functions of the Act. Sections 
111(d) and 129(b)(3) of the Act authorize the EPA to develop a Federal 
plan for States that do not submit approvable State plans.
2. EPA's Legal Authority in Indian Country
    Section 301(a) provides EPA with the authority to administer 
Federal programs in Indian country. Section 301(d)(4) of the Act 
authorizes the Administrator to directly administer provisions of the 
Act where Tribal implementation of those provisions is not appropriate 
or administratively not feasible. See section I.D. of this preamble for 
a more detailed discussion of EPA's authority to administer the HMIWI 
Federal plan in Indian country.
    The EPA is proposing this Federal regulation under the legal 
authority of the Act to implement the emission guidelines in those 
States and areas of Indian country not covered by an approved plan. As 
discussed in section IV of this document, implementation and 
enforcement of the Federal plan may be delegated to Tribal, State, or 
local agencies when requested by a State, Tribal, or local agency, and 
when EPA determines that such delegation is appropriate.

B. Inventory of Affected HMIWI

    A State or Tribal plan must include an inventory of HMIWI affected 
by the emission guidelines. 40 CFR 60.25(a). Consistent with this 
requirement, docket number A-98-24, item II-B-1 contains an inventory 
of all the HMIWI EPA is aware of that will be covered by this proposed 
Federal plan.
    This inventory was initially created in 1995 in connection with 
development of the HMIWI emission guidelines. In late 1998, EPA gave 
States an opportunity to submit updates to the 1995 list. Many States 
responded and in most cases, EPA was able to incorporate these updates. 
However, EPA recognizes that this list may not be complete. Therefore, 
sources subject to this Federal plan would include, but would not be 
limited to, the HMIWI listed in docket A-98-24, item II-B-1. States, 
Tribes, or individuals with corrections to the Federal plan inventory 
are invited to submit their corrections during the comment period for 
this proposal.
    Hospital/medical/infectious waste incinerators that are located in 
a State

[[Page 36430]]

or Tribal area with an approved and effective plan, but that are not 
covered by such plan (for example, because they were inadvertently 
omitted from the coverage of the plan and the plan fails to contain 
language that would include inadvertently omitted HMIWI), would 
automatically be covered by the Federal plan. There will be no need to 
reopen the Federal plan to add such HMIWI.

C. Inventory of Emissions

    A State plan must include an emissions estimate for HMIWI subject 
to the emission guidelines. 40 CFR 60.25(a). The pollutants to be 
inventoried are dioxins/furans, cadmium (Cd), lead (Pb), mercury (Hg), 
particulate matter (PM), hydrogen chloride (HCl), nitrogen oxides 
(NOX), carbon monoxide (CO), and sulfur dioxide 
(SO2). For this proposal, EPA has estimated the emissions 
from each HMIWI that would be covered by the Federal plan for the nine 
pollutants regulated by the Federal plan. This emissions inventory is 
included in item II-B-1 in docket A-98-24.
    Pollutant emissions are expressed in kilograms per year (kg/yr) for 
most pollutants and grams per year (g/yr) for dioxins/furans. The 
emissions inventory is based on available information about the HMIWI 
and emission factors developed for purposes of calculating nationwide 
air impacts of the emission guidelines. Refer to the emissions 
estimates memorandum in docket A-98-24 (item II-B-1) for the complete 
emissions inventory and details on the calculations.

D. Emission Limits

    A State plan must include emission limits. 40 CFR 60.24(a). Section 
129(b)(2) of the Act requires these emission limits to be ``at least as 
protective as'' those in the emission guidelines. The emission limits 
in this proposed HMIWI Federal plan are the same as those contained in 
the emission guidelines.
    The HMIWI source category is divided into three subcategories based 
on waste burning capacity: Small (200 pounds per hour [1b/
hr]), medium (>200 to 500 lb/hr), and large (>500 lb/hr). Separate 
emission limits apply to each subcategory of existing HMIWI. Small 
HMIWI that meet certain ``rural criteria'' are allowed to meet less 
stringent emission limits. The numerical emission limits and additional 
requirements are summarized in section VI of this preamble.

E. Increments of Progress

    Increments of progress are required for HMIWI that need more than 1 
year from State plan approval to comply, or in the case of the Federal 
plan, more than 1 year after promulgation of the final Federal plan. 40 
CFR 60.24(e)(1). Increments of progress are necessary in order to 
ensure that HMIWI needing more time to comply are making progress 
toward meeting the emission limits. This proposed HMIWI Federal plan 
includes as its compliance schedule the same five increments of 
progress from 40 CFR 60.21(h), as required by 40 CFR 60.24(e)(1), along 
with defined and enforceable dates for completion of each increment.
1. How EPA Determined the Compliance Schedule
    The increments of progress and the time proposed for their 
completion are based on case studies conducted by EPA of eight HMIWI 
that completed retrofits of the types of controls needed to meet the 
subpart Ce emission limits. These case studies are documented in docket 
A-98-24, item II-A-1. Based on these case studies, it appears that some 
HMIWI may need more than 1 year to retrofit with controls. Using the 
schedules from the case studies as a basis, the EPA determined the 
proper intervals for each of the subpart B increments.
    To ensure compliance, the five increments of progress proposed for 
the Federal plan are the minimum increments of progress allowed by 
subpart B, see 40 CFR 60.21(h), and are found at proposed 
Sec. 62.14470(b) of subpart HHH. The following increments would apply 
to all HMIWI, regardless of category or size, that require longer than 
1 year after the promulgation date of this Federal plan to comply:
    (1) Submit final control plan;
    (2) Award contracts for control systems or process modifications or 
orders for purchase of components;
    (3) Begin onsite construction or installation of the air pollution 
control device(s) or process changes;
    (4) Complete onsite construction or installation of the air 
pollution control device(s) or process changes; and
    (5) Final compliance.
    Subpart Ce suggests additional increments of progress, however, the 
EPA is proposing not to include additional increments of progress. By 
not imposing additional increments of progress, EPA hopes to minimize 
burden on the industry that could result with more increments. EPA, 
however, solicits comment on whether additional increments are 
warranted.
2. Owner/Operator Responsibilities
    The HMIWI owner or operator is responsible for meeting each of the 
five increments of progress for each HMIWI unit no later than the 
applicable compliance date. The owner or operator must notify EPA as 
each increment of progress is achieved, as well as when any is missed. 
The notification must identify the increment and the date the increment 
is achieved (or missed). If an owner or operator misses an increment 
deadline, the owner or operator must also notify EPA when the increment 
is finally achieved. The owner or operator must mail the notification 
to the applicable EPA Regional Office within 10 business days after the 
increment date defined in the Federal plan. (See Table 1 under the FOR 
FURTHER INFORMATION CONTACT section of this document for a list of 
Regional Offices.)
    The definition of each increment of progress, along with its 
proposed completion date, follows.
    Submit Final Control Plan. To meet this increment, the owner or 
operator of each HMIWI must submit a plan that describes, at a minimum, 
the air pollution control devices and/or process changes that will be 
employed so that each HMIWI complies with the emission limits and other 
requirements. A final control plan is not required for units that will 
be shut down.
    Completion date: September 15, 2000.
    Award Contract. To award a contract means the HMIWI owner or 
operator enters into legally binding agreements or contractual 
obligations that cannot be canceled or modified without substantial 
financial loss to the owner or operator. The EPA anticipates that the 
owner or operator may award a number of contracts to complete the 
retrofit. To meet this increment of progress, the HMIWI owner or 
operator must award a contract or contracts to initiate onsite 
construction, to initiate onsite installation of air pollution control 
devices, and/or to incorporate process changes. The owner or operator 
must mail a copy of the signed contract(s) to EPA within 10 business 
days of entering the contract(s).
    Completion date: April 15, 2001.
    Begin Onsite Construction. To begin onsite construction, 
installation of air pollution control devices, or process change means 
to begin any of the following:

    (1) Installation of an air pollution control device in order to 
comply with the final emission limits as outlined in the final 
control plan;
    (2) Physical preparation necessary for the installation of an 
air pollution control device in order to comply with the final 
emission limits as outlined in the final control plan;
    (3) Alteration of an existing air pollution control device in 
order to comply with the final emission limits as outlined in the 
final control plan;

[[Page 36431]]

    (4) Alteration of the waste combustion process to accommodate 
installation of an air pollution control device in order to comply 
with the final emission limits as outlined in the final control 
plan; or
    (5) Process changes identified in the final control plan in 
order to meet the emission standards.

    Completion date: December 15, 2001.
    Complete Onsite Construction. To complete onsite construction means 
that all necessary air pollution control devices or process changes 
identified in the final control plan are in place, onsite, and ready 
for operation on the HMIWI.
Completion date: July 15, 2002.
    Final Compliance. To be in final compliance means to incorporate 
all process changes or complete retrofit construction in accordance 
with the final control plan and to connect the air pollution control 
equipment or process changes such that if the HMIWI is brought on line 
all necessary process changes or air pollution control equipment will 
operate as designed.
    Completion date: September 15, 2002.
    The EPA believes this compliance schedule is achievable and 
necessary based on the following:

    (1) When determining completion dates for the increments of 
progress, EPA applied the maximum amount of time that most HMIWI in 
the case study needed in order to comply;
    (2) Since September 15, 1997 when the emission guidelines were 
promulgated, HMIWI owners and operators have known that they would 
need to make process changes or install controls by September 15, 
2002; and
    (3) The EPA believes that a compliance schedule with enforceable 
increments of progress is necessary to ensure final compliance by 
September 15, 2002.

3. Failure to Comply

    If an HMIWI does not achieve final compliance by September 15, 
2002, this proposed Federal plan would require the HMIWI to shut down 
by September 15, 2002, complete the retrofit while not operating, and 
be in compliance upon restarting. Shut down is necessary in order to 
avoid being out of compliance and subject to possible enforcement 
action.

F. Waste Management Plan Requirements

    Under the emission guidelines, State plans must require owners and 
operators of HMIWI to develop waste management plans in compliance with 
40 CFR 60.55c. See 40 CFR 60.35e. The proposed HMIWI Federal plan 
includes the same requirement (see proposed 40 CFR 62.14430 and 
62.14431 of subpart HHH).

G. Testing, Monitoring, Inspection, Recordkeeping, and Reporting 
Requirements

    Under the emission guidelines, State plans must include the 
testing, monitoring, recordkeeping, and reporting requirements set 
forth at 40 CFR 60.37e and 60.38e of subpart Ce. The proposed HMIWI 
Federal plan includes virtually the same requirements (see proposed 40 
CFR 62.14450 through 62.14455 and Secs. 62.14460 through 62.14465 of 
subpart HHH).
    Minor changes are proposed to the testing and monitoring 
requirements to clarify the meaning of those requirements and to insert 
some text that was inadvertently omitted from the emission guidelines. 
Subpart Ce specifies a 3-hour rolling average when monitoring maximum 
charge rate. While this is correct for continuous and intermittent 
HMIWI, it is not correct for batch HMIWI. For batch HMIWI, the 
requirement is proposed to be a daily average, consistent with the 
definition of maximum charge rate for batch units.

H. Operator Training and Qualification Requirements

    Under the emission guidelines, State plans must include the 
operator training and qualification requirements set forth at 40 CFR 
60.53c. See 40 CFR 60.34e. The proposed HMIWI Federal plan includes 
these requirements as well (see proposed 40 CFR 62.14420 through 
62.14425 of subpart HHH).

I. Record of Public Hearings

    A State must provide opportunity for public participation in 
adopting the State plan. See 40 CFR 60.23(c). In adopting any HMIWI 
Federal plan, the EPA will hold public hearing(s) at appropriate 
Regional Offices, if requested. A record of the public hearing(s), if 
any, will appear in the docket.

J. Progress Reports

    Under the emission guidelines, States or Tribes with approved and 
effective plans must send annual progress reports to the appropriate 
Regional Office to show their progress toward implementation of the 
emission guidelines. 40 CFR 60.25(e). Under the Federal plan, the EPA 
Regional Offices will prepare these progress reports. States or Tribes 
that have been delegated the authority to implement and enforce this 
Federal plan would also be required to submit annual progress reports 
to the appropriate EPA Regional Office.
    Appendix D of 40 CFR part 60 requires reporting of emissions data 
to the Aerometric Emissions Information Retrieval System Facility 
Subsystem (AIRS). These reports can be combined with the State 
implementation plan report required by 40 CFR 51.321 in order to avoid 
double reporting. Under the proposed Federal plan, EPA Regional Offices 
would report AIRS emissions data. If a State or Tribe has been 
delegated the authority to implement and enforce the Federal plan, the 
State or Tribe would report emissions data to AIRS.
    Each progress report must include the following items: (1) Status 
of enforcement actions; (2) status of increments of progress; (3) 
identification of sources that have shut down or started operation; (4) 
emission inventory data for sources that were not in operation at the 
time of plan development, but that began operation during the reporting 
period; (5) additional data as necessary to update previously submitted 
source and emission information; and (6) copies of technical reports on 
any performance testing and monitoring.

III. HMIWI That Have or Will Shut Down

A. Inoperable Units

    In cases where an HMIWI has shut down and does not intend to 
restart, the HMIWI may be left off the source inventory in a State, 
Tribal, or this Federal plan if it is rendered inoperable. The HMIWI 
owner/operator may do the following to render an HMIWI inoperable: (1) 
Weld the waste charge door shut, (2) remove stack (and by-pass stack, 
if applicable), (3) remove combustion air blowers, and/or (4) remove 
burners or fuel supply.

B. HMIWI That Have Shut Down

    Hospital/medical/infectious waste incinerators that are known to 
have already shut down (but are not known to be inoperable) are 
included in the source inventory of this proposed Federal plan. Such 
units must also be identified in any State or Tribal plan submitted to 
EPA.
1. Restarting Before September 15, 2002
    If the owner or operator of an inactive HMIWI plans to restart 
before September 15, 2002, the owner or operator would be required to 
submit a control plan for the HMIWI and bring the HMIWI into compliance 
with the applicable compliance schedule. Final compliance is required 
for all pollutants and all HMIWI no later than September 15, 2002. (See 
section II.E for the discussion on compliance schedules and increments 
of progress.)

[[Page 36432]]

2. Restarting After September 15, 2002
    Under this proposed Federal plan, a control plan would not be 
needed for inactive HMIWI that restart after September 15, 2002. 
However, before restarting, such HMIWI would have to complete the 
operator training and qualification requirements and inspection 
requirements (if applicable) and complete retrofit or process 
modifications upon restarting. Performance testing to demonstrate 
compliance would be required within 180 days after restarting. There 
would be no need to show that the increments of progress have been met 
since these steps would have occurred before restart while the HMIWI 
was shut down and not generating emissions. An HMIWI that operates out 
of compliance after September 15, 2002 would be in violation of the 
Federal plan and subject to enforcement action.

IV. Implementation of the Federal Plan and Delegation

A. Background of Authority

    Under sections 111(d) and 129(b) of the Act, EPA is required to 
adopt emission guidelines that are applicable to existing solid waste 
incineration sources. These emission guidelines are not enforceable 
until EPA approves a State or Tribal plan or adopts a Federal plan that 
implements and enforces them, and the State, Tribal, or Federal plan 
has become effective. As discussed above, the Federal plan regulates 
HMIWI in States or Tribal areas that do not have approved plans in 
effect.
    Congress has determined that the primary responsibility for air 
pollution prevention and control rests with State and local agencies. 
See section 101(a)(3) of the Act. Consistent with that overall 
determination, Congress established sections 111 and 129 of the Act 
with the intent that the States and local agencies take the primary 
responsibility for ensuring that the emission limitations and other 
requirements in the emission guidelines are achieved. Also, in section 
111(d) of the Act, Congress explicitly required that EPA establish 
procedures that are similar to those under section 110(c) for State 
Implementation Plans. Although Congress required EPA to propose and 
promulgate a Federal plan for States that fail to submit approvable 
State plans on time, EPA strongly encourages States to submit 
approvable plans. The EPA strongly encourages States that are unable to 
submit approvable plans to request delegation of the Federal plan so 
that they can have primary responsibility for implementing the emission 
guidelines, consistent with Congress' intent.
    Approved and effective State plans or delegation of the Federal 
plan is EPA's preferred outcome since EPA believes that State and local 
agencies not only have the responsibility to carry out the emission 
guidelines, but also have the ``insider'' knowledge and enforcement 
resources critical to achieving the highest rate of compliance. For 
these reasons, EPA will do all that it can to expedite delegation of 
the Federal plan to State and local agencies, whenever possible.
    The EPA also believes that Indian tribes are the primary parties 
responsible for regulating air quality within Indian country. See EPA's 
Indian Policy (``Policy for Administration of Environmental Programs on 
Indian Reservations,'' signed by William D. Ruckelshaus, Administrator 
of EPA, dated November 4, 1984, reaffirmed in 1994 in a memorandum 
entitled ``EPA Indian Policy,'' signed by Carol M. Browner, 
Administrator of EPA, dated March 14, 1994).

B. Delegation of the Federal Plan and Retained Authorities

    If a State or Indian tribe intends to take delegation of the 
Federal plan, the State or Indian tribe must submit to the appropriate 
EPA Regional Office a written request for delegation of authority. The 
State or Indian tribe must explain how it meets the criteria for 
delegation. See generally ``Good Practices Manual for Delegation of 
NSPS and NESHAP'' (EPA, February 1983). In order to obtain delegation, 
an Indian tribe must also establish its eligibility to be treated in 
the same manner as a State (section I.D. of the preamble). The letter 
requesting delegation of authority to implement the Federal plan must 
demonstrate that the State or Tribe has adequate resources, as well as 
the legal and enforcement authority to administer and enforce the 
program. A Memorandum of Agreement (MOA) between the State or Tribe and 
the EPA would set forth the terms and conditions of the delegation, the 
effective date of the agreement, and would also serve as the mechanism 
to transfer authority. Upon signature of the agreement, the appropriate 
EPA Regional Office would publish an approval notice in the Federal 
Register, thereby incorporating the delegation authority into the 
appropriate subpart of 40 CFR part 62.
    If authority is not delegated to a State or Indian tribe, EPA will 
implement the Federal plan. Also, if a State or Tribe fails to properly 
implement a delegated portion of the Federal plan, EPA will assume 
direct implementation and enforcement of that portion. The EPA will 
continue to hold enforcement authority along with the State or Tribe 
even when a State or Tribe has received delegation of the Federal plan. 
In all cases where the Federal plan is delegated, the EPA will retain 
and will not transfer authority to a State or Tribe to approve the 
following items:

    (1) Alternative site-specific operating parameters established 
by facilities using HMIWI controls other than a wet scrubber or dry 
scrubber followed by a fabric filter; and
    (2) Alternative methods of demonstrating compliance.

    Hospital/medical/infectious waste incinerator owners or operators 
who wish to establish alternative operating parameters or alternative 
methods of demonstrating compliance should submit a request to the 
Regional Office Administrator with a copy to the appropriate State or 
Tribe.

C. Mechanisms for Transferring Authority

    There are two mechanisms for transferring implementation authority 
to States, Tribes, and local agencies: (1) EPA approval of a State or 
Tribal plan after the Federal plan is in effect; and (2) if a State or 
Tribe does not submit or obtain approval of its own plan, EPA 
delegation to a State or Tribe of the authority to implement certain 
portions of this Federal plan to the extent appropriate and if allowed 
by State or Tribal law. Both of these options are described in more 
detail below.
1. State or Tribe Submits a Plan After HMIWI Located in the Area Are 
Subject to the Federal Plan
    After HMIWI in a State or Tribal area become subject to the Federal 
plan, the State, Tribal, or local agency may still adopt and submit a 
plan to EPA. If EPA determines that the State or Tribal plan is as 
protective as the emission guidelines, EPA will approve the State or 
Tribal plan. If EPA determines that the plan is not as protective as 
the emission guidelines, EPA will disapprove the plan and the HMIWI 
covered in the State or Tribal plan would remain subject to the Federal 
plan until a State or Tribal plan covering those HMIWI is approved and 
effective.
    Upon the effective date of a State or Tribal plan, the Federal plan 
would no longer apply to HMIWI covered by such plan and the State, 
Tribal, or local agency would implement and enforce the State or Tribal 
plan in lieu of the Federal plan. When an EPA Regional Office approves 
a State or Tribal plan, it will amend the appropriate subpart of 40 CFR 
part 62 to indicate such approval.

[[Page 36433]]

2. State Takes Delegation of the Federal Plan
    State, Tribal, or local agencies may assume implementation of this 
Federal plan. As discussed above, EPA believes that it is advantageous 
and the best use of resources for State, Tribal, or local agencies to 
agree to undertake, on EPA's behalf, administrative and substantive 
roles in implementing the Federal plan to the extent appropriate and 
where authorized by State or Tribal law. These functions could include 
administration and oversight of compliance reporting and recordkeeping 
requirements, HMIWI inspections, and preparation of draft notices of 
violation. The EPA would retain responsibility for bringing enforcement 
actions against sources violating Federal plan provisions.

V. Title V Operating Permits

    Section 502(a) of the Act requires sources ``subject to standards 
or regulations under section 111'' to obtain title V operating permits. 
See also 40 CFR 70.3(a)(2) and 71.3(a)(2). Because EPA is proposing 
this Federal plan under sections 111 and 129 of the Act, sources 
subject to this Federal plan must obtain title V permits. Those title V 
permits must assure compliance with all applicable requirements for the 
source, including all applicable requirements of this Federal plan. See 
40 CFR 70.6(a)(1), 70.2, 71.6(a)(1) and 71.2.
    Under section 129(e) of the Act, owners or operators of HMIWI 
subject to this Federal plan must operate pursuant to a title V permit 
no later than 36 months after promulgation of the HMIWI emission 
guidelines (i.e., by September 15, 2000), or by the effective date of 
the State, Tribal, or Federal title V permit program that covers the 
area in which the unit is located, whichever is later. If an owner or 
operator is required to obtain a title V permit for the first time by 
virtue of being subject to the Federal plan, the owner or operator must 
submit a complete title V permit application by the applicable permit 
deadline (i.e., by September 15, 2000) or the effective date of the 
State, Tribal, or Federal operating permits program, whichever is 
later.b
---------------------------------------------------------------------------

    \b\ Section 503(d) of the Act and 40 CFR 70.7(b) and 71.7(b) 
allow a source to operate without being in violation of title V once 
the source has submitted a timely and complete permit application, 
even if the source has not yet received a final title V operating 
permit from the permitting authority. To this end, the application 
should be submitted early enough for the permitting authority to 
find the application either complete or incomplete before the 
application deadline. In the event the application is found 
incomplete by the permitting authority, the source must submit the 
information needed to make the application complete by the 
application deadline in order to obtain the application shield. See 
proposed 40 CFR 62.14481 and 40 CFR 70.5(a)(2) and 71.5(a)(2).
---------------------------------------------------------------------------

    An earlier permit deadline may apply if an HMIWI is subject to 
title V for another reason. For example, an HMIWI might already be 
subject to title V as a result of being a major source under one or 
more of three major source definitions in title V--section 112, section 
302, or part D of title I of the Act. See 40 CFR 70.3(a)(1) and 
71.3(a)(1) (subjecting major sources to title V permitting) and 
Secs. 70.2 and 71.2 (defining major source for purposes of title V). An 
HMIWI might also already be subject to title V if it is subject to some 
other earlier promulgated standard under section 111 or 112 of the Act. 
See 40 CFR 70.3(a)(2) and (3), 71.3(a)(2) and (3). If an owner or 
operator is already subject to title V by virtue of some other 
requirement and has submitted a timely and complete permit application 
but the title V permit has not yet been released by the permitting 
authority, then the owner or operator should supplement its title V 
application by including the applicable requirements of the Federal 
plan in accordance with 40 CFR 70.5(b) or 71.5(b).
    If an owner or operator of an HMIWI is already subject to title V 
by virtue of some other requirement on the effective date of this 
Federal plan and already possesses a title V permit with a remaining 
term of 3 or more years, then the owner or operator will receive from 
its permitting authority a notice of intent to reopen the title V 
permit to include the requirements of the Federal plan in accordance 
with the procedures established in 40 CFR 70.7(f) or 71.7(f). An owner 
or operator of an HMIWI with a title V permit having a remaining term 
of less than 3 years on the effective date of this Federal plan need 
not modify its title V permit, as a matter of Federal law, to include 
the Federal plan requirements until that permit is renewed.c 
However, the owner or operator remains subject to, and must act in 
compliance with, the Federal plan requirements.
---------------------------------------------------------------------------

    \c\ See CAA section 502(b)(6); 40 CFR 70.7(f)(1)(I) and 
71.7(f)(1)(I). The CAA authorizes State, Tribal and Federal 
operating permit programs to require permits to be reopened and 
modified to incorporate the requirements of the Federal plan when 
fewer than 3 years remaining on a source's permit, however, so 
permitting authorities could reopen permits sooner than required by 
Federal law. Such reopenings should be completed no later than 18 
months after promulgation of the applicable requirement. Any sources 
in this situation may wish to consult their operating permit program 
regulations or permitting authorities to determine whether revisions 
to their permits are necessary to incorporate the Federal plan 
requirements.
---------------------------------------------------------------------------

    Owners or operators of combustors that burn only pathological 
waste, low-level radioactive waste, and/or chemotherapeutic waste and 
co-fired combustors, as defined in this proposed Federal plan, must 
comply only with certain recordkeeping and reporting requirements set 
forth in the proposed Federal plan. See proposed Sec. 62.14400. They 
are not subject to the other substantive emissions control-related 
requirements of the Federal plan as long as they comply with the 
recordkeeping and reporting requirements set forth as conditions for 
their exemption. Owners and operators of these sources are not required 
to obtain title V operating permits as a matter of Federal law if the 
only reason they would potentially be subject to title V is these 
nonemissions control-related recordkeeping and reporting requirements. 
See proposed Sec. 62.14480. The EPA interprets the CAA and the 
regulations at parts 70 and 71 to mean that these sources are ``not 
subject to standards or regulations under section 111'' for purposes of 
title V permitting. See CAA section 502(a) and 40 CFR 70.3(a)(2) and 
71.3(a)(2). Therefore, these sources would not be required to apply for 
title V permits on the basis of the applicability of recordkeeping and 
reporting requirements necessary to qualify for exemption from the 
substantive emissions control-related requirements of this proposed 
Federal plan. However, owners and operators of sources that burn only 
pathological waste, low-level radioactive waste, and/or 
chemotherapeutic waste, and co-fired combustors, that do not comply 
with the recordkeeping and reporting requirements necessary to qualify 
for exemption from the other requirements of the Federal plan would 
become subject to those other requirements and would have to obtain 
title V permits. Moreover, if, in the future, EPA promulgates 
regulations subjecting any of these sources to substantive requirements 
other than these recordkeeping and reporting requirements, these 
sources could become subject to title V at that time.
    Section 502(a) of the Act requires title V permits of listed 
sources, including any source ``subject to standards or regulations 
under section 111 * * *.'' See also 40 CFR 70.3(a)(2) and 71.3(a)(2). 
The EPA reads the recordkeeping and reporting requirements of this 
proposed Federal plan, which are simply conditions for exemption from 
the other substantive emissions control-related requirements of the 
Federal plan, not to be requirements that would make a source ``subject 
to'' a section 111 standard (here the HMIWI Federal plan) within the

[[Page 36434]]

meaning of these statutory and regulatory provisions. Accordingly, 
HMIWI that comply with the recordkeeping and reporting requirements 
necessary for their exemption from the other substantive emissions 
control-related requirements of the Federal plan are not ``subject to'' 
the Federal plan solely for purposes of being required to obtain a 
title V permit. Hospital/medical/ infectious waste incinerators that 
are subject to Federal plan requirements other than these recordkeeping 
or reporting conditions as well as HMIWI that fail to comply with any 
of the conditions for exemption from these other substantive emissions 
control-related Federal plan requirements are subject to title V 
permitting under section 502(a).
    It is worth noting that section 502(a) of the Act also provides a 
mechanism for the Administrator to ``promulgate regulations to exempt'' 
one or more source categories from title V permitting requirements, if 
EPA finds that compliance with such requirements is ``impracticable, 
infeasible, or unnecessarily burdensome on such categories, except that 
the Administrator may not exempt any major source from such 
regulations.'' The EPA is not invoking this mechanism to justify its 
conclusion that the HMIWI discussed above are not required to obtain 
title V permits. These HMIWI have not been ``exempted'' from title V 
within the meaning of the last sentence of section 502(a), and the 
Agency does not purport to have made the statutory showing of 
impracticability, infeasibility or unnecessary burden for these 
sources. Rather, the Agency believes that the recordkeeping and 
reporting requirements with which these HMIWI must comply are not the 
type of requirements that make them ``subject to'' a standard or 
regulation under section 111 within the meaning of the first sentence 
of section 502(a). In EPA's view, HMIWI in this unique position do not 
even meet the threshold criteria for sources required to obtain title V 
permits under section 502(a) of the Act.
    In addition to being consistent with the governing statutory 
provisions, EPA believes this approach is sound and environmentally 
protective. Where HMIWI have only recordkeeping and/or reporting 
obligations designed to show they are not subject to the other 
requirements of the Federal plan, EPA does not believe that it makes 
sense to compel them to obtain title V permits based upon a possible 
technical argument that in that minimal sense they are subject to the 
subpart for purposes of section 502(a) of the Act. Moreover, because 
these HMIWI may well not currently be covered by applicable Federal 
requirements other than this Federal plan's recordkeeping and reporting 
requirements, a contrary approach would lead to the paradoxical and 
unreasonable result that these HMIWI would be obtaining title V permits 
whose sole requirements were conditions demonstrating their exemption 
from the other substantive requirements of the Federal standard that 
triggered the need to obtain a permit.
    In addition to the likely bareness of these HMIWI title V permits, 
the applicability and compliance provisions these HMIWI must meet are 
simpler than the usual applicable requirements in a title V permit. 
Therefore, the multiple, sometimes complex applicability determinations 
so integral to the title V permit issuance process are accomplished 
here through simple notifications to EPA (or delegated EPA Regional 
Office, State, or Tribe). While title V permits are important in 
helping States and Tribes, EPA, sources, and the public assure 
compliance with a source's Clean Air Act obligations, the Agency does 
not believe this objective would be significantly advanced by these 
sources obtaining title V permits, particularly not to a degree that 
would outweigh the time, resources, expense and permit fees associated 
with the permit process in this instance. The EPA believes the approach 
described herein comports with the Act and Federal regulations, 
represents a sensible solution to these uniquely situated sources, and 
affords the environmental protection demanded by the law.

VI. Owner/Operator Responsibilities

    The proposed HMIWI Federal rule (40 CFR part 62, subpart HHH) which 
will implement this Federal plan includes emission limits, monitoring 
and performance testing requirements, inspection requirements (for 
small rural HMIWI only), waste management plan requirements, operator 
training and qualification requirements, and recordkeeping and 
reporting requirements. These emission standards and requirements are 
the same as those in the emission guidelines (40 CFR part 60, subpart 
Ce). The requirements are summarized in this section.

A. Applicability

    The HMIWI Federal plan would apply to existing HMIWI that are not 
covered by an approved and effective State or Tribal plan or are 
located in a State or Tribal area that has incorrectly submitted a 
negative declaration. An existing HMIWI is an HMIWI for which 
construction commenced on or before June 20, 1996. Hospital/medical/
infectious waste incinerators for which construction commenced after 
June 20, 1996 or modification commenced after March 16, 1998 are not 
subject to the Federal plan; they are new sources and are subject to 
the 40 CFR part 60 subpart Ec New Source Performance Standards (NSPS). 
An HMIWI is defined as any device that combusts any amount of medical/
infectious waste or hospital waste. The terms ``medical/infectious 
waste'' and ``hospital waste'' are defined in proposed Sec. 62.14490 of 
subpart HHH.
    Incinerators that burn only pathological, low-level radioactive, or 
chemotherapeutic waste (all defined in proposed Sec. 62.14490 of 
subpart HHH) are required to notify EPA of an exemption claim and keep 
records of the periods of time when only pathological, low-level 
radioactive, or chemotherapeutic waste is burned. However, these HMIWI 
are not subject to the other substantive requirements of the Federal 
plan during periods when they burn such wastes provided that they 
comply with the applicable notification and recordkeeping requirements. 
Existing incinerators, processing operations, or boilers that cofire 
hospital waste and/or medical/infectious waste with other fuels or 
wastes and combust 10 percent or less combined medical/infectious and 
hospital waste by weight (on a calendar quarter basis) are also not 
subject to the other substantive requirements of the Federal plan 
provided they file an exemption claim and keep records of the amounts 
of each fuel and waste burned. Any unit required to have a permit under 
section 3005 of the Solid Waste Disposal Act is exempt from the Federal 
plan, as are municipal waste combustors subject to 40 CFR part 60 
subparts Cb, Ea, or Eb. Finally, pyrolysis units (as defined at 40 CFR 
62.14490 of subpart HHH) and cement kilns firing hospital waste and/or 
medical/infectious waste are also not subject to this Federal plan.
    The HMIWI source category is divided into small (200 lb/
hr), medium (>200 to 500 lb/hr), and large (>500 lb/hr) subcategories 
based on waste burning capacity. Waste burning capacity is determined 
either by the maximum design capacity or by the ``maximum charge rate'' 
established during the most recent performance test. In other words, a 
source may change its size designation by establishing an enforceable 
``maximum charge rate'' lower than its design capacity. For example, a 
``medium'' unit with a design capacity of 250 lb/hr may establish a 
maximum charge rate of 200

[[Page 36435]]

lb/hr and be considered a ``small'' unit for purposes of the Federal 
plan. Separate requirements apply to each subcategory of existing 
HMIWI.

B. Emission Limits

    Table 1 of subpart HHH provides the emission limits for existing 
HMIWI covered by the proposed Federal plan. In addition to the emission 
limits presented in Table 1, all HMIWI are subject to a 10 percent 
stack opacity limitation. Stack opacity will be determined using EPA 
Reference Method 9.
    The Federal plan contains alternative emission limits for small 
HMIWI that meet the following ``rural criteria'': (1) The small HMIWI 
is located at least 50 miles from the nearest Standard Metropolitan 
Statistical Area (SMSA) boundary; and (2) the small HMIWI burns no more 
than 2,000 pounds of hospital waste and medical/infectious waste per 
week. For this Federal plan, the list of areas comprising each SMSA as 
of June 30, 1993 (defined by the Office of Management and Budget (OMB)) 
will be used to determine whether a small HMIWI meets the ``rural 
criteria.'' The list of areas comprising each SMSA is presented in OMB 
Bulletin No. 93-17 entitled ``Revised Statistical Definitions for 
Metropolitan Areas.'' This document is available for public inspection 
and copying at EPA's Air and Radiation Docket and Information Center 
(docket A-91-61, item IV-J-125). See the ADDRESSES section at the 
beginning of this preamble for the telephone number and location of the 
docket. In addition, OMB Bulletin No. 93-17 is available at: http://
www.census.gov/population/estimates/metro-city/93mfips.txt, or from 
National Technical Information Services, 5285 Port Royal Road, 
Springfield, Virginia 22161, (703) 487-4650 (document number PB 93-192-
664). The alternative emission limits for small HMIWI that meet the 
rural criteria are provided in Table 1 of subpart HHH.

C. Additional Requirements

    This section presents the other major provisions of the Federal 
plan for HMIWI. With the exception of the emission limits referenced 
above and the compliance and performance testing requirements and the 
inspection requirements described in this section, HMIWI that meet the 
small rural criteria are to comply with the same additional 
requirements as all other existing HMIWI. This section does not attempt 
to show all requirements of the Federal plan. The regulatory text of 
subpart HHH contains a full and comprehensive statement of the 
requirements of the proposed Federal plan.
    The proposed Federal plan contains operator training and 
qualification requirements for all HMIWI. Each facility would be 
required to have at least one trained and qualified operator on duty or 
on-call. The trained and qualified operator must pass an HMIWI operator 
training course and meet qualification requirements. Also, each 
facility would be required to develop site-specific HMIWI operating 
procedures. Employees involved with HMIWI operation must review the 
site-specific operating information annually.
    The proposed Federal plan would require all facilities to develop a 
waste management plan that identifies the feasibility and approach of 
separating certain components of the healthcare waste stream in order 
to reduce the amount of toxic emissions from incinerated waste.
    The compliance and performance testing requirements in the proposed 
Federal plan differ for small rural HMIWI and for all other HMIWI. 
Small rural HMIWI would be required to conduct an initial performance 
test to determine compliance with the PM, CO, CDD/CDF, and Hg emission 
limits and opacity limit, and establish operating parameters. In 
addition, small rural HMIWI would be required to conduct annual tests 
to determine compliance with the opacity limit.
    The compliance and performance testing requirements in the proposed 
Federal plan would require facilities with small non-rural, medium, and 
large HMIWI to conduct an initial performance test to determine 
compliance with the PM, CO, CDD/CDF, HCl, Pb, Cd, and Hg emission 
limits and opacity limit, and establish operating parameters. These 
HMIWI would also be required to conduct annual performance tests to 
determine compliance with the PM, CO, and HCl emission limits and 
opacity limit. The proposed Federal plan would allow facilities to 
conduct performance tests for PM, CO, and HCl every third year if the 
previous three performance tests demonstrate that the facility is in 
compliance with the emission limits for PM, CO, and HCl.
    The proposed Federal plan contains monitoring requirements for all 
HMIWI. Each facility would be required to install and maintain 
equipment to continuously monitor operating parameters including 
secondary chamber temperature, waste feed rate, bypass stack, and air 
pollution control device (APCD) operating parameters as appropriate. 
The proposed Federal plan would require facilities to obtain monitoring 
data at all times during HMIWI operation.
    In addition, the proposed Federal plan contains reporting and 
recordkeeping requirements for all HMIWI. Facilities would be required 
to maintain records for 5 years of results from the initial performance 
test and all subsequent performance tests, operating parameters, 
inspections (small rural HMIWI only), and operator training and 
qualification. Facilities would be required to submit the results of 
the initial performance test and all subsequent performance tests, and 
to submit reports on emission rates or operating parameters that have 
not been recorded or which exceeded applicable limits.
    A summary of dates for compliance with the Federal plan for HMIWI 
is presented in Table 3.

VII. Administrative Requirements

    This section addresses the following administrative requirements: 
Docket, Paperwork Reduction Act, Executive Orders 12866, 12875, 13045, 
and 13084, Unfunded Mandates Reform Act, Regulatory Flexibility Act, 
Small Business Regulatory Enforcement Fairness Act, and the National 
Technology Transfer and Advancement Act. Since today's proposed rule 
merely implements the emission guidelines promulgated on September 15, 
1997 (codified at 40 CFR part 60, subpart Ce) as they apply to HMIWI 
and does not impose any new requirements, much of the following 
discussion of administrative requirements refers to the documentation 
of applicable administrative requirements in the preamble to the 1997 
rule promulgating the emission guidelines (62 FR 48347-48379, September 
15, 1997).

A. Docket

    The docket is intended to be an organized and complete file of the 
administrative records compiled by EPA. The docket is a dynamic file 
because material is added throughout the rulemaking process. The 
docketing system is intended to allow members of the public and 
industries involved to readily identify and locate documents so they 
can effectively participate in the rulemaking process. Along with 
proposed and promulgated standards and their preambles, the contents of 
the docket (with limited exceptions) will serve as the record in the 
case of judicial review. See section 307(d)(7)(A) of the Act.
    As discussed above, a docket has been prepared for this action 
pursuant to the procedural requirements of section 307(d) of the Act, 
42 U.S.C. 7607(d). Docket number A-91-61 contains the technical support 
for the September 15, 1997 emission guidelines. Docket number A-98-24 
contains additional supporting information for this proposed rule.

B. Paperwork Reduction Act

    The information collection requirements in this proposed rule have 
been submitted for approval to the OMB under the Paperwork Reduction 
Act, 44 U.S.C. 3501 et seq. An information collection request (ICR) 
document has been prepared by EPA (ICR No. 1899.01) and a copy may be 
obtained from Ms. Sandy Farmer by mail at OP Regulatory Information 
Division, U. S. Environmental Protection Agency (2137), 401 M Street, 
SW., Washington, DC 20460; by E-mail at [email protected]; or by 
calling (202) 260-2740. A copy may also be downloaded off the Internet 
at http://www.epa.gov/icr.
    This ICR reflects the burden estimate for the emission guidelines 
which were promulgated in the Federal Register on September 15, 
1997.d The burden estimate includes the burden associated 
with State/Tribal plans as well as the burden associated with today's 
proposed Federal plan. Consequently, the burden estimates described 
below overstate the information collection burden associated with the 
Federal plan. However, upon approval by EPA, a State/Tribal plan 
becomes Federally enforceable. Therefore, it is important to estimate 
the full burden associated with the State/Tribal plans and the Federal 
plan. As State/Tribal plans are approved, the Federal plan burden will 
decrease, but the overall burden of the State/Tribal plans and the 
Federal plan will remain the same.
---------------------------------------------------------------------------

    \d\ In promulgating the September 15, 1997 rule setting the NSPS 
and emission guidelines, EPA assessed only the ICR requirements 
associated with the NSPS. See 62 FR at 48373-74.
---------------------------------------------------------------------------

    The information collected would be used by EPA to ensure that the 
HMIWI regulatory requirements are implemented and are complied with on 
a continuous basis. Records and reports would be necessary to enable 
EPA to identify existing HMIWI that may not be in compliance with the 
HMIWI regulatory requirements. Based on reported information, EPA would 
decide which units should be inspected and what records or processes 
should be inspected. The records that owners and operators of existing 
HMIWI maintain would indicate to EPA whether personnel are operating 
and maintaining control equipment properly.
    Based on the inventory of HMIWI used to develop the emission 
guidelines, the HMIWI regulatory requirements (i.e., the State/Tribal 
plans and Federal plan) are projected to affect approximately 2,373 
existing HMIWI in the United States or protectorates. A number of State 
plans are expected to be approved within the year following Federal 
plan promulgation. When a State plan is approved, the Federal plan will 
no longer apply to HMIWI covered in that State plan.
    The estimated average annual burden for industry for the first 3 
years after the promulgation of the emission guidelines would be 
133,404 hours annually at a cost of $5,858,292 per year to meet the 
monitoring, recordkeeping, and reporting requirements. The estimated 
average annual burden, over the first 3 years, for the regulatory 
agencies (State and Federal) would be 10,984 hours at a cost of 
$438,736 (including travel expenses) per year.
    Burden means total time, effort, or financial resources expended by 
persons to generate, maintain, retain, disclose, or provide information 
to or for a regulatory agency. This includes the time needed to do the 
following: review instructions; develop, acquire, install, and use 
technology and systems for the purposes of collecting and validating 
information; process, maintain, and disclose information; amend 
previously applicable instructions and requirements to reflect new 
HMIWI State or Federal plan requirements; train personnel to respond to 
a collection of information; search data sources; complete and review 
the collection of information; and transmit or otherwise disclose the 
information. An agency may not conduct or sponsor, and a person is not 
required to respond to, a collection of information unless it displays 
a currently valid OMB control number. The OMB control numbers for EPA's 
regulations are listed in 40 CFR part 9 and 48 CFR part 15.
    Send comments on the Agency's need for this information, the 
accuracy of the burden estimates provided, and any suggested methods 
for minimizing respondent burden, including the use of automated 
collection techniques to the Director, OP Regulatory Information 
Division, U. S. Environmental Protection Agency (2137), 401 M Street, 
SW., Washington, DC 20460; and to the Office of Information and 
Regulatory Affairs, Office of Management and Budget, 725 17th Street, 
NW.,

[[Page 36437]]

Washington, DC 20503, marked ``Attention: Desk Officer for EPA.'' 
Include the ICR number in any correspondence. Because OMB is required 
to make a decision on the ICR between 30 and 60 days after today's 
request for comment, a comment to OMB is best assured of having its 
full effect if OMB receives it by August 5, 1999. The final rule will 
respond to any OMB or public comments on the information collection 
requirements contained in this proposal.

C. Executive Order 12866

    Under Executive Order 12866, 58 FR 51735, (October 4, 1993), EPA 
must determine whether the regulatory action is ``significant'' and, 
therefore, subject to OMB review and the requirements of the Executive 
Order. The EPA considered the 1997 emission guidelines to be 
significant and the rules were reviewed by OMB in 1997. See 62 FR 
48374. The Federal plan proposed today would simply implement the 1997 
emission guidelines and does not result in any additional control 
requirements or impose any additional costs above those previously 
considered during promulgation of the 1997 emission guidelines. 
Therefore, this regulatory action is considered ``not significant'' 
under Executive Order 12866.

D. Executive Order 12875

    Under Executive Order 12875, 58 FR 58093 (October 26, 1993), EPA 
may not issue a regulation that is not required by statute and that 
creates a mandate upon a State, local, or Tribal government, unless the 
Federal government provides the funds necessary to pay the direct 
compliance costs incurred by those governments or EPA consults with 
those governments. If EPA complies by consulting, Executive Order 12875 
requires EPA to provide to OMB a description of the extent of EPA's 
prior consultation with representatives of affected State, local, and 
Tribal governments, the nature of their concerns, any written 
communications from the governments, and a statement supporting the 
need to issue the regulation. In addition, Executive Order 12875 
requires EPA to develop an effective process permitting elected 
officials and other representatives of State, local, and Tribal 
governments ``to provide meaningful and timely input in the development 
of regulatory proposals containing significant unfunded mandates.''
    Today's rule does not create a mandate on State, local, or Tribal 
governments. The rule does not impose any enforceable duties on these 
entities. Moreover, this Federal plan simply implements the 1997 
emission guidelines and does not result in any additional control 
requirements or impose any additional costs above those previously 
considered during promulgation of the 1997 emission guidelines. 
Accordingly, the requirements of section 1(a) of Executive Order 12875 
do not apply to this rule.

E. Executive Order 13045

    Executive Order 13045, ``Protection of Children from Environmental 
Health Risks and Safety Risks,'' 62 FR 19885 (April 23, 1997), applies 
to any rule that: (1) Is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate affect on children. If the regulatory action 
meets both criteria, the Agency must evaluate the environmental health 
or safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
feasible alternatives considered by the Agency.
    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under section 5-501 of the Order has the 
potential to influence the regulation. This proposed rule is not 
subject to Executive Order 13045 because (1) it is not an economically 
significant regulatory action as defined by Executive Order 12866, and 
(2) it is based on technology performance and not on health or safety 
risks.

F. Executive Order 13084

    Under Executive Order 13084, 63 FR 27655 (May 19, 1998), EPA may 
not issue a regulation that is not required by statute, that 
significantly or uniquely affects the communities of Indian Tribal 
governments, and that imposes substantial direct compliance costs on 
those communities, unless the Federal government provides the funds 
necessary to pay the direct compliance costs incurred by the Tribal 
governments, or EPA consults with those governments. If EPA complies by 
consulting, Executive Order 13084 requires EPA to provide to the OMB, 
in a separately identified section of the preamble to the rule, a 
description of the extent of EPA's prior consultation with 
representatives of affected Tribal governments, a summary of the nature 
of their concerns, and a statement supporting the need to issue the 
regulation. In addition, Executive Order 13084 requires EPA to develop 
an effective process permitting elected officials and other 
representatives of Indian Tribal governments ``to provide meaningful 
and timely input in the development of regulatory policies on matters 
that significantly or uniquely affect their communities.''
    The Federal plan proposed today does not significantly or uniquely 
affect communities of Indian Tribal governments. The proposed Federal 
plan would not impose any enforceable duties on those governments. 
Moreover, this Federal plan simply implements the 1997 emission 
guidelines and does not result in any additional control requirements 
or impose any additional costs above those previously considered during 
promulgation of the 1997 emission guidelines. Thus, the requirements of 
section 3(b) of Executive Order 13084 do not apply to this rule.

G. Unfunded Mandates Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Pub. 
L. 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and Tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures by State, local, and Tribal governments, in 
the aggregate, or by the private sector, of $100 million or more in any 
1 year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost effective or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost effective, or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted.
    Before EPA establishes any regulatory requirements that may 
significantly or uniquely affect small governments, including Tribal 
governments, it must have developed under section 203 of the UMRA a 
small government agency plan. The plan must provide for notifying 
potentially affected small governments, enabling officials of affected 
small governments to have meaningful and

[[Page 36438]]

timely input in the development of EPA regulatory proposals with 
significant Federal intergovernmental mandates, and informing, 
educating, and advising small governments on compliance with the 
regulatory requirements.
    An unfunded mandates statement was prepared and published in the 
preamble to the September 15, 1997 NSPS and emission guidelines. See 62 
FR at 48374-78. The EPA has determined that the proposed HMIWI Federal 
plan does not include any new Federal mandates or additional 
requirements above those previously considered during promulgation of 
the 1997 emission guidelines. Therefore, the requirements of the UMRA 
do not apply to this proposed rule.

H. Regulatory Flexibility Act and Small Business Regulatory Enforcement 
Fairness Act

    The Regulatory Flexibility Act (RFA) of 1980, as amended by the 
Small Business Regulatory Enforcement Fairness Act (SBREFA), 5 U.S.C. 
601 et seq., requires Federal agencies to give special consideration to 
the impacts of regulations on small entities, which are defined as 
small businesses, small organizations, and small governments. During 
the 1997 HMIWI emission guidelines rulemaking, EPA estimated that small 
entities would not be affected by the promulgated emission guidelines 
and standards, and therefore, a regulatory flexibility analysis was not 
required. See 62 FR at 48378-79. This proposed Federal plan would not 
establish any new requirements. Therefore, pursuant to the provisions 
of 5 U.S.C. 605(b), EPA certifies that this Federal plan will not have 
a significant impact on a substantial number of small entities, and 
thus a regulatory flexibility analysis is not required.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Pub L. 104-113, section 12(d), 15 U.S.C. 272 
note, directs EPA to use voluntary consensus standards in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. Voluntary consensus standards 
are technical standards (e.g., materials specifications, test methods, 
sampling procedures, and business practices) that are developed or 
adopted by voluntary consensus standards bodies. The NTTAA directs EPA 
to provide Congress, through OMB, explanations when the Agency decides 
not to use available and applicable voluntary consensus standards.
    The NTTAA does not apply because the proposed Federal plan would 
implement an existing rule to which NTTAA did not apply. In addition, 
the emission guidelines, which the Federal plan is based on, does not 
require new technology or impose new technical standards.

Sec. 62.14401  How do I determine if my HMIWI is covered by an approved 
and effective State or Tribal plan?

    This part (40 CFR part 62) contains a list of all States and Tribal 
areas with approved Clean Air Act section 111(d)/129 plans in effect. 
However, this part is only updated once a year. Thus, if this part does 
not indicate that your State or Tribal area has an approved and 
effective plan, you should contact your State environmental agency's 
air director or your EPA Regional Office to determine if approval 
occurred since publication of the most recent version of this part.


Sec. 62.14402  If my HMIWI is not listed on the Federal plan inventory, 
am I exempt from this subpart?

    Not necessarily. Sources subject to this subpart include, but are 
not limited to, the inventory of sources listed in docket A-98-24 for 
the Federal plan.


Sec. 62.14403  What happens if I modify an existing HMIWI?

    (a) If you commenced modification (defined in Sec. 62.14490) of an 
existing HMIWI after March 16, 1998, you are subject to 40 CFR part 60, 
subpart Ec (40 CFR 60.50c through 60.58c) and you are not subject to 
this subpart, except as provided in paragraph (b) of this section.
    (b) If you made physical or operational changes to your existing 
HMIWI solely for the purpose of complying with this subpart, these 
changes are not considered a modification, and you are not subject to 
40 CFR part 60, subpart Ec (40 CFR 60.50c through 60.58c). You remain 
subject to this subpart.

Emission Limits


Sec. 62.14410  Are there different emission limits for different 
locations and sizes of HMIWI?

    Yes, there are different emission limits for small rural, small, 
medium, and large HMIWI. To determine the size category of your HMIWI, 
consult the definitions in Sec. 62.14490.


Sec. 62.14411  What emission limits apply to my HMIWI?

    You must operate your HMIWI in compliance with the emission limit 
requirements for your HMIWI size category listed in Table 1 of this 
subpart.

[[Page 36440]]

Sec. 62.14412  What stack opacity requirements apply?

    Your HMIWI (regardless of size category) must not discharge into 
the atmosphere from the stack any gases that exhibit greater than 10 
percent opacity (6-minute block average).


Sec. 62.14413  When do the emission limits and stack opacity 
requirements apply?

    The emission limits and stack opacity requirements of this subpart 
apply at all times except during periods of startup, shutdown, or 
malfunction, provided that no hospital waste or medical/infectious 
waste is charged to your HMIWI during periods of startup, shutdown, or 
malfunction.

    Yes. All HMIWI owners or operators must have a waste management 
plan.


Sec. 62.14431  What must my waste management plan include?

    Your waste management plan must identify both the feasibility of, 
and the approach for, separating certain components of solid waste from 
the health care waste stream in order to reduce the amount of toxic 
emissions from incinerated waste. The waste management plan you develop 
may address, but is not limited to, paper,

[[Page 36441]]

cardboard, plastics, glass, battery, or metal recycling, or purchasing 
recycled or recyclable products. Your waste management plan may include 
different goals or approaches for different areas or departments of the 
facility and need not include new waste management goals for every 
waste stream. When you develop your waste management plan it should 
identify, where possible, reasonably available additional waste 
management measures, taking into account the effectiveness of waste 
management measures already in place, the costs of additional measures, 
the emission reductions expected to be achieved, and any other 
potential environmental or energy impacts they might have. In 
developing your waste management plan, you must consider the American 
Hospital Association publication entitled ``An Ounce of Prevention: 
Waste Reduction Strategies for Health Care Facilities.'' This 
publication (AHA Catalog No. 057007) is available for purchase from the 
American Hospital Association (AHA) Service, Inc., Post Office Box 
92683, Chicago, Illinois 60675-2683.


Sec. 62.14432  When must my waste management plan be completed?

    As specified in Sec. 62.14463 and Sec. 62.14464, you must submit 
your waste management plan with your initial report, which is due 60 
days after your initial performance test.

Inspection Requirements


Sec. 62.14440  Which HMIWI are subject to inspection requirements?

    Only small rural HMIWI (defined in Sec. 62.14490) are subject to 
inspection requirements.


Sec. 62.14441  When must I inspect my small rural HMIWI?

    You must complete any necessary repairs within 10 operating days of 
the inspection unless you obtain written approval from the EPA 
Administrator (or delegated enforcement authority) establishing a 
different date when all necessary repairs of your HMIWI must be 
completed.

Compliance, Performance Testing, and Monitoring Requirements


Sec. 62.14450  What are the testing requirements for small rural HMIWI?

    (a) If you operate a small rural HMIWI (defined in Sec. 62.14490), 
you must conduct an initial performance test for PM, opacity, CO, 
dioxin/furan, and Hg using the test methods and procedures outlined in 
Sec. 62.14452.
    (b) After the initial performance test is completed or is required 
to be completed under Sec. 62.14470, whichever date comes first, if you 
operate a small rural HMIWI you must determine compliance with the 
opacity limit by conducting an annual performance test (no more than 12 
months following the previous performance test) using the applicable 
procedures and test methods listed in Sec. 62.14452.
    (c) The 2,000 lb/wk limitation for small rural HMIWI does not apply 
during performance tests.
    (d) The EPA Administrator may request a repeat performance test at 
any time.


Sec. 62.14451  What are the testing requirements for HMIWI that are not 
small rural?

    (a) If you operate an HMIWI that is not a small rural HMIWI, you 
must conduct an initial performance test for PM, opacity, CO, dioxin/
furan, HCl, Pb, Cd, and Hg using the test methods and procedures 
outlined in Sec. 62.14452.
    (b) After the initial performance test is completed or is required 
to be completed under Sec. 62.14470, whichever date comes first, you 
must:
    (1) Determine compliance with the opacity limit by conducting an 
annual performance test (no more than 12 months following the previous 
performance test) using the applicable procedures and test methods 
listed in Sec. 62.14452.
    (2) Determine compliance with the PM, CO, and HCl emission limits 
by conducting an annual performance test (no more than 12 months 
following the previous performance test) using the applicable 
procedures and test methods listed in Sec. 62.14452. If all three 
performance tests over a 3-year period indicate compliance with the 
emission limit for a pollutant (PM, CO, or HCl), you may forego a 
performance test for that pollutant for the next 2 years. At a minimum, 
you must conduct a performance test for PM, CO, and HCl every third 
year (no more than 36 months following the previous performance test). 
If a performance test conducted every third year indicates compliance 
with the emission limit for a pollutant (PM, CO, or HCl), you may 
forego a performance test for that pollutant for an additional 2 years. 
If any performance test indicates noncompliance with the respective 
emission limit, you must conduct a performance test for that pollutant 
annually until all annual performance tests over a 3-year period 
indicate compliance with the emission limit.
    (c) The EPA Administrator may request a repeat performance test at 
any time.


Sec. 62.14452  What test methods and procedures must I use?

    You must use the following test methods and procedures to conduct 
performance tests to determine compliance with the emission limits:
    (a) All performance tests must consist of a minimum of three test 
runs conducted under representative operating conditions;
    (b) The minimum sample time must be 1 hour per test run unless 
otherwise indicated in this section;

[[Page 36442]]

    (c) You must use EPA Reference Method 1 of 40 CFR part 60, appendix 
A to select the sampling location and number of traverse points;
    (d) You must use EPA Reference Method 3, 3A, or 3B of 40 CFR part 
60, appendix A for gas composition analysis, including measurement of 
oxygen concentration. You must use EPA Reference Method 3, 3A, or 3B of 
40 CFR part 60, appendix A simultaneously with each reference method;
    (e) You must adjust pollutant concentrations to 7 percent oxygen 
using the following equation:

Cadj = Cmeas (20.9-7)/(20.9-%O2)

Where:

Cadj = pollutant concentration adjusted to 7 percent oxygen;
Cmeas = pollutant concentration measured on a dry basis at 
standard conditions
(20.9-7) = 20.9 percent oxygen--7 percent oxygen (defined oxygen 
correction basis);
20.9 = oxygen concentration in air, percent; and
%O2 = oxygen concentration measured on a dry basis at 
standard conditions, percent.

    (f) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 5 or 29 of 40 CFR part 60, appendix A to 
measure particulate matter emissions;
    (g) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 9 of 40 CFR part 60, appendix A to measure 
stack opacity;
    (h) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 10 or 10B of 40 CFR part 60, appendix A to 
measure the CO emissions;
    (i) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 23 of 40 CFR part 60, appendix A to measure 
total dioxin/furan emissions. The minimum sample time must be 4 hours 
per test run. If you have selected the toxic equivalency standards for 
dioxin/furans under Sec. 62.14411, you must use the following 
procedures to determine compliance:
    (1) Measure the concentration of each dioxin/ furan tetra- through 
octa-congener emitted using EPA Reference Method 23;
    (2) For each dioxin/furan congener measured in accordance with 
paragraph (i)(1) of this section, multiply the congener concentration 
by its corresponding toxic equivalency factor specified in Table 2 of 
this subpart;
    (3) Sum the products calculated in accordance with paragraph (i)(2) 
of this section to obtain the total concentration of dioxins/furans 
emitted in terms of toxic equivalency.
    (j) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 26 of 40 CFR part 60, appendix A to measure 
HCl emissions. If you have selected the percentage reduction standards 
for HCl under Sec. 62.14411, compute the percentage reduction in HCl 
emissions (%RHCl) using the following formula:
[GRAPHIC] [TIFF OMITTED] TP06JY99.000

Where:

%RHCl = percentage reduction of HCl emissions achieved;
Ei = HCl emission concentration measured at the control 
device inlet, corrected to 7 percent oxygen (dry basis at standard 
conditions); and
Eo = HCl emission concentration measured at the control 
device outlet, corrected to 7 percent oxygen (dry basis at standard 
conditions).

    (k) Except as provided in paragraph (l) of this section, you must 
use EPA Reference Method 29 of 40 CFR part 60, appendix A to measure 
Pb, Cd, and Hg emissions. If you have selected the percentage reduction 
standards for metals under Sec. 62.14411, compute the percentage 
reduction in emissions (%Rmetal) using the following 
formula:
[GRAPHIC] [TIFF OMITTED] TP06JY99.001

Where:

%Rmetal = percentage reduction of metal emission (Pb, Cd, or 
Hg) achieved;
Ei = metal emission concentration (Pb, Cd, or Hg) measured 
at the control device inlet, corrected to 7 percent oxygen (dry basis 
at standard conditions); and
Eo = metal emission concentration (Pb, Cd, or Hg) measured 
at the control device outlet, corrected to 7 percent oxygen (dry basis 
at standard conditions).

    (l) If you are using a continuous emission monitoring system (CEMS) 
to demonstrate compliance with any of the emission limits under 
Sec. 62.14411 or Sec. 62.14412, you must:
    (1) Determine compliance with the appropriate emission limit(s) 
using a 12-hour rolling average, calculated each hour as the average of 
the previous 12 operating hours (not including startup, shutdown, or 
malfunction). Performance tests using EPA Reference Methods are not 
required for pollutants monitored with CEMS.
    (2) Operate a CEMS to measure oxygen concentration, adjusting 
pollutant concentrations to 7 percent oxygen as specified in paragraph 
(e) of this section.
    (3) Operate all CEMS in accordance with the applicable procedures 
under appendices B and F of 40 CFR part 60.
    (m) Use of the bypass stack during a performance test will 
invalidate the performance test.


Sec. 62.14453  What must I monitor?

    (a) If your HMIWI is a small rural HMIWI, or your HMIWI is equipped 
with a dry scrubber followed by a fabric filter, a wet scrubber, or a 
dry scrubber followed by a fabric filter and wet scrubber:
    (1) You must establish the appropriate maximum and minimum 
operating parameters, indicated in Table 3, as site-specific operating 
parameters during the initial performance test to determine compliance 
with the emission limits; and
    (2) After the date on which the initial performance test is 
completed or is required to be completed under Sec. 62.14470, whichever 
comes first, your HMIWI must not operate above any of the applicable 
maximum operating parameters or below any of the applicable minimum 
operating parameters listed in Table 3 and measured as 3-hour rolling 
averages (calculated each hour as the average of the previous 3 
operating hours), at all times except during startup, shutdown, 
malfunction, and performance tests.
    (b) If your HMIWI is not a small rural HMIWI, and you are using an 
air pollution control device other than a dry scrubber followed by a 
fabric filter, a wet scrubber, or a dry scrubber followed by a fabric 
filter and a wet scrubber to comply with the emission limits under 
Sec. 62.14411, you must petition the EPA Administrator for site-
specific operating parameters to be established during the initial 
performance test and you must continuously monitor those parameters 
thereafter. You may not conduct the initial performance test until the 
EPA Administrator has approved the petition.


Sec. 62.14454  How must I monitor the required parameters?

    (a) You must install, calibrate (to manufacturers' specifications), 
maintain, and operate devices (or establish methods) for monitoring the 
applicable maximum and minimum operating parameters listed in Table 3 
of this subpart such that these devices (or methods) measure and record 
values for the operating parameters at the

[[Page 36443]]

frequencies indicated in Table 3 of this subpart at all times except 
during periods of startup and shutdown. For charge rate, the device 
must measure and record the date, time, and weight of each charge fed 
to the HMIWI. This must be done automatically, meaning that the only 
intervention from an operator during the process would be to load the 
charge onto the weighing device. For batch HMIWI, the maximum charge 
rate is measured on a daily basis (the amount of waste charged to the 
unit each day).
    (b) For all HMIWI except small rural HMIWI, you must install, 
calibrate (to manufacturers' specifications), maintain, and operate a 
device or method for measuring the use of the bypass stack, including 
the date, time, and duration of such use.
    (c) For all HMIWI except small rural HMIWI, if you are using 
controls other than a dry scrubber followed by a fabric filter, a wet 
scrubber, or a dry scrubber followed by a fabric filter and a wet 
scrubber to comply with the emission limits under Sec. 62.14411, you 
must install, calibrate (to manufacturers' specifications), maintain, 
and operate the equipment necessary to monitor the site-specific 
operating parameters developed pursuant to Sec. 62.14453(b).
    (d) You must obtain monitoring data at all times during HMIWI 
operation except during periods of monitoring equipment malfunction, 
calibration, or repair. At a minimum, valid monitoring data must be 
obtained for 75 percent of the operating hours per day for 90 percent 
of the operating days per calendar quarter that your HMIWI is 
combusting hospital waste and/or medical/infectious waste.


Sec. 62.14455  What if my HMIWI goes outside of a parameter limit?

    (a) Operation above the established maximum or below the 
established minimum operating parameter(s) constitutes a violation of 
established operating parameter(s). Operating parameter limits do not 
apply during startup, shutdown, malfunction, and performance tests.
    (b) Except as provided in paragraph (f) or (g) of this section, if 
your HMIWI is a small rural HMIWI,

Permitting Obligation


Sec. 62.14480  Does this subpart require me to obtain an operating 
permit under title V of the Clean Air Act and implementing regulations?

    This subpart requires you to obtain an operating permit under title 
V of the Clean Air Act and implementing regulations (``title V 
permit'') unless you are only subject to the recordkeeping and 
reporting requirements listed at Secs. 62.14400(b)(1) or (b)(2). Also, 
if you own or operate a unit described in Secs. 62.14400(b)(3), (b)(4), 
(b)(5) or (b)(6), you are not subject to any requirements

[[Page 36447]]

of this subpart; therefore, this subpart does not require you to obtain 
a title V permit.


Sec. 62.14481  When must I submit a title V permit application for my 
HMIWI?

    You must submit a title V permit application in time for it to be 
determined or deemed complete by no later than September 15, 2000 or by 
the effective date of a title V permit program in the State or Tribal 
area in which the unit is located, whichever is later. (An earlier 
deadline may apply if your HMIWI is also subject to title V's 
permitting requirements because of some other triggering requirement.) 
A ``complete'' title V permit application is one that has been approved 
by the appropriate permitting authority as complete under section 503 
of the Clean Air Act and 40 CFR parts 70 and 71. It is not enough to 
have submitted a title V permit application by September 15, 2000 
because the application must be determined or deemed complete by the 
permitting authority by that date for your HMIWI to operate after that 
date in compliance with Federal law.
