Approval and Promulgation of Implementation Plan; Michigan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The United States Environmental Protection Agency approves the 
State Implementation Plan (SIP) revision submitted by the State of 
Michigan for the purpose of establishing new Reasonably Available 
Control Technology (RACT) rules for sources of volatile organic 
compounds (VOCs). On June 12, 1993 and November 12, 1993 the Michigan 
Department of Natural Resources (MDNR) submitted VOC rules to the EPA 
as proposed revisions to Michigan's ozone SIP. These revisions address 
deficiencies listed in letters dated December 11, 1990 and August 23, 
1991 to the State of Michigan commenting on proposed State regulations 
(addressing the requirement of the Clean Air Act, as amended in 1990, 
(Act) that States correct deficient VOC RACT rules (``fix-up'' 
requirement)) and the requirement of the Act that States adopt VOC RACT 
rules where not previously required (``catch-up'' requirement). 
Further, these revisions address deficiencies in Rules 628 and 629 
which were disapproved on December 12, 1993 (58 FR 64678). The 
rationale for the approval is set forth in this final rule; additional 
information is available at the address indicated. Elsewhere in this 
Federal Register, EPA is proposing approval of, and soliciting public 
comment on, this requested SIP revision. If adverse comments are 
received on this direct final rule, EPA will withdraw this final rule 
and address the comments received in the final action on the proposed 
rule published in the proposed rules section of this Federal Register. 
Unless this final rule is withdrawn, no further rulemaking will occur 
on this requested SIP revision.

DATES: This final rule will be effective November 7, 1994, unless 
notice is received by October 7, 1994, that someone wishes to submit 
adverse comments. If the effective date is delayed, timely notice will 
be published in the Federal Register.

ADDRESSES: Written comments should be sent to: Carlton T. Nash, Chief, 
Regulation Development Section, Air Toxics and Radiation Branch (AT-
18J), EPA, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 
60604-3590.

    Copies of the SIP revision request and the EPA's analysis are 
available for inspection at the following address: (It is recommended 
that you telephone Douglas Aburano at (312) 353-6960 before visiting 
the Region 5 office.) EPA, Region 5, Air and Radiation Division, 77

SUPPLEMENTARY INFORMATION:

I. Background

    Under section 107 of the Clean Air Act, as amended in 1977 (1977 
Act), EPA designated certain areas in each State as not attaining the 
National Ambient Air Quality Standards (NAAQS) for ozone. For Michigan, 
see 43 FR 8962 (March 3, 1978) and 43 FR 45993 (October 5, 1978). For 
these areas, section 172(a) of the 1977 Act, required that the State 
revise its SIP to provide for attaining the primary NAAQS as 
expeditiously as practicable, but not later than December 31, 
1982.1
---------------------------------------------------------------------------

    \1\The 1977 Act's requirements for an approvable SIP are 
described in a ``General Preamble'' for part D rulemaking published 
at 44 FR 20372 (April 4, 1979), 44 FR 38583 (July 2, 1979), 44 FR 
50371 (August 28, 1979), 44 FR 53761 (September 17, 1979), and 44 FR 
67182 (November 23, 1979).
---------------------------------------------------------------------------

    Sections 172 (b) and (c) of the 1977 Act require that for 
stationary sources, an approvable SIP must include legally enforceable 
requirements reflecting the application of RACT to sources of VOC 
emissions. For the purpose of assisting State and local agencies in 
developing RACT rules, EPA prepared three groups of Control Techniques 
Guideline (CTG) documents which each establish the presumptive norm for 
RACT for a specific source category. In cases where the State adopts 
rules that are less stringent than in the CTG, the State must justify 
that those rules are RACT for that source or source category. In 
partial response to the requirement for VOC RACT rules, the State of 
Michigan submitted and EPA approved controls representing the 
application of RACT for certain stationary sources of VOCs covered by 
the first two groups of CTGs (RACT I--40 CFR 52.1170(c)(16) (45 FR 
29790); 40 CFR 52.1170(c)(39) (46 FR 43422); 40 CFR 52.1170(c)(56) (47 
FR 32116) and RACT II--40 CFR 52.1170(c)(56) (47 FR 32116)).
    Section 172 of the 1977 Act authorized EPA to grant extensions to 
those States that could not demonstrate attainment of the ozone 
standard by December 31, 1982 if certain conditions were met by the 
States in revising their air pollution control program. These areas 
became known as extension areas. Michigan requested and received an 
extension to December 31, 1987 for achieving the ozone NAAQS in Wayne, 
Oakland and Macomb Counties. This extension was granted on June 2, 1980 
(45 FR 37196) and obligated the State to develop, for those counties, 
RACT regulations for sources that are addressed by the Group III CTGs 
(RACT III) and RACT regulations for major sources that are not 
addressed by a CTG (major non-CTG RACT).2
---------------------------------------------------------------------------

    \2\On January 22, 1981, (46 FR 7182), USEPA published guidance 
for the development of 1982 ozone SIPs in ``State Implementation 
Plans: Approval of 1982 Ozone and Carbon Monoxide Plan Revisions for 
Areas Needing an Attainment Date Extension''.
---------------------------------------------------------------------------

    On May 26, 1988 pursuant to section 110(a)(2)(H) of the 1977 Act, 
EPA Region 5 notified Governor James J. Blanchard that the Michigan SIP 
was substantially inadequate to attain and maintain the ozone standard 
and requested that deficiencies in the existing SIP be corrected (EPA's 
SIP-Call). Among other deficiencies, EPA noted that the State had not 
yet submitted the RACT regulations for sources in Wayne, Oakland and 
Macomb Counties that were covered by the third set of CTGs.
    On November 15, 1990 the Clean Air Act Amendments of 1990 were 
enacted. Public Law 101-549, 104 Stat. 2399 (codified at 42 U.S.C. 7401 
et seq.). By operation of law, the Detroit area, including Wayne, 
Oakland and Macomb Counties, retained its nonattainment designation and 
was classified as a moderate nonattainment area for ozone. Section 
182(a)(2)(A) of the Act requires each State to submit to EPA by May 15, 
1991 revisions or additions to its SIP to correct deficiencies in its 
RACT rules for ozone. Section 182(a)(2)(A) of the Act applies to those 
ozone nonattainment areas classified as marginal or above, and requires 
States to adopt and correct RACT rules for such areas pursuant to pre-
amended section 172(b) as interpreted in pre-amendment guidance.3 
Because the Detroit area (including Wayne, Oakland and Macomb Counties) 
is classified as moderate, the area is subject to this RACT ``fix-u'' 
requirement and the May 15, 1991 deadline.
---------------------------------------------------------------------------

    \3\Among other things, the pre-amendment guidance consists of 
those portions of the proposed Post-1987 Ozone and Carbon Monoxide 
Policy that concern RACT, 52 FR 45044 (November 24, 1987); ``Issues 
Relating to VOC Regulation Cutpoints, Deficiencies and Deviations, 
Clarification to appendix D of November 24, 1987 Federal Register 
Notice'' (Blue Book) (notice of availability was published in the 
Federal Register on May 25, 1988); and the existing control 
technique guidelines (CTGs).
---------------------------------------------------------------------------

    Other areas within Michigan also retained a designation of 
nonattainment and were classified by operation of law upon enactment. 
These areas are also subject to the RACT fix-up requirement. However, 
under EPA's pre-amendment guidance4 interpreting the requirements 
of section 172(b) these areas were not required to adopt RACT rules for 
sources covered by the Group III CTGs. Therefore, for purposes of the 
May 15, 1991 deadline, only three counties were required to have RACT 
rules for Group III CTG sources.
---------------------------------------------------------------------------

    \4\The two memoranda are: May 21, 1984 memorandum entitled, 
``Confirmation That Volatile Organic Compound (VOC) Regulations Are 
Required for Source Categories for Which Control Techniques 
Guidelines Have Been Issued'' and a June 25, 1984 memorandum 
entitled, ``Applicability of Group III Control Techniques 
Guidelines'' under the same signature.
---------------------------------------------------------------------------

    Areas that are designated nonattainment, that are classified as 
moderate or above, and that were not previously required to adopt RACT 
rules for sources covered by the Group III CTGs, are required to adopt 
such rules under section 182(b)(2) of the amended Act.\5\ Section 
182(b)(2) requires that these areas adopt RACT rules for: (1) Each 
category of VOC sources in the area covered by a CTG document issued by 
the Administrator between the date of enactment of the 1990 Amendments 
and the date of attainment, by a date specified by the Administrator; 
(2) all VOC sources in the area covered by any CTG issued before the 
date of enactment; and (3) all other major stationary sources of VOCs 
that are located in the area, by November 15, 1992. The requirements of 
section 182(b)(2) are also referred to as ``catch-up'' requirements. 
For these areas, RACT rules for the Group III CTGs are due on November 
15, 1992.
---------------------------------------------------------------------------

    \5\This requirement would apply to the remainder of the Detroit 
nonattainment area as well as the Grand Rapids (Kent and Ottawa 
Counties), and Muskegon (Muskegon County) areas which are all 
designated as nonattainment and classified as moderate.
---------------------------------------------------------------------------

    On April 28, 1989 MDNR submitted final regulations to satisfy 
outstanding commitments in its 1982 ozone SIP for southeast Michigan 
(Wayne, Oakland and Macomb Counties). The regulations submitted 
addressed RACT III categories for fugitive VOC leaks from synthetic 
organic chemical manufacturing industries (SOCMI) and natural gas 
plants, Rules 628 and 629, as well as non-CTG categories for paint and 
resin manufacturing and coating of auto, truck, and business machine 
parts. These are rules 630, 631, and 632, respectively. At the time 
MDNR submitted these rules, EPA only required adoption of rules for 
Ract III categories in extension areas. However, MDNR chose to expand 
the applicability of these rules to all of the counties listed in EPA's 
SIP-Call, which include the Detroit, Grand Rapids, and Muskegon areas. 
This submittal, therefore, addressed requirements of EPA's SIP-Call, 
section 182(a)(2)(A) of the Act (for Wayne, Oakland, and Macomb 
Counties), and section 182(b)(2) of the Act (for Livingston, Monroe, 
St. Clair, Washtenaw, Kent, Ottawa, and Muskegon Counties).
    On December 9, 1993 EPA disapproved two of the five RACT III 
category rules (58 FR 40759). The rules disapproved were those that 
covered VOC leaks from synthetic organic chemical and polymer 
manufacturing plants (Rule 628) and natural gas processing plants (Rule 
629).
    On June 12, 1993 MDNR submitted final regulations to satisfy the 
section 182(a)(2)(A) fix-up requirements of the Act. Included in these 
regulations were changes meant to address deficiencies listed in EPA's 
May 26, 1988 SIP call. Since MDNR chose to expand the coverage of these 
regulations to all of the 10 ozone nonattainment counties classified as 
moderate (Michigan has no ozone nonattainment classifications above 
moderate), this submittal also addressed requirements under section 
182(b)(2). EPA found this submittal to be complete in a letter dated 
June 28, 1993 from Valdas Adamkus, EPA's Region 5 Administrator, to 
Roland Harmes, Director of MDNR. This letter stopped a sanctions 
process which was initiated on October 22, 1991 for failure to submit a 
SIP revision to fulfill the fix-up requirements.
    Under a cover letter dated November 15, 1993 MDNR submitted final 
regulations to satisfy the remaining deficiencies not addressed in the 
June 12, 1993 submittal, to correct deficiencies cited in the December 
9, 1993 disapproval of Rules 628 and 629, and to satisfy the catch-up 
requirements of section 182(b)(2) of the Act. A letter dated April 18, 
1994 from Valdas Adamkus to Roland Harmes found the November 15, 1993 
submittal complete for the Detroit--Ann Arbor area and halted the 
sanctions process which was started on January 15, 1993 for a failure 
to submit these regulations. The clock for the Muskegon and Grand 
Rapids areas continued to run because of an outstanding item which was 
not submitted for the western portion of the State.
    A finding of completeness was made in a July 14, 1994 letter from 
Valdas Adamkus to Roland Harmes for the Grand Rapids and Muskegon 
areas. This finding was in response to the submittal of a non-CTG SIP 
submittal made for the western portion of the State and halted the last 
of the sanction clocks that were started on January 15, 1993 for the 
State of Michigan.
    This document proposes approval of the final regulations submitted 
by MDNR on June 12, 1993 and November 15, 1993 for incorporation into 
Michigan's ozone SIP.

II. EPA's Evaluation and Proposed Action

    In determining the approvability of a VOC rule, EPA must evaluate 
the rule for consistency with the requirements of the Act and EPA 
regulations, as found in section 110 and part D of the Act and 40 CFR 
part 51 (Requirements for Preparation, Adoption, and Submittal of 
Implementation Plans). The EPA interpretation of these requirements, 
which forms the basis for this action, appears in the various EPA 
policy guidance documents listed in footnote 3. Among these provisions 
is the requirement that a VOC rule must, at a minimum, provide for the 
implementation of RACT for existing major stationary sources of VOC 
emissions. This requirement was carried forth from the pre-amended Act.
    Under the amended Act, Congress ratified EPA's use of CTG 
documents, as well as other Agency policy, for requiring States to 
``fix-up'' their RACT rules. See section 182(a)(2)(A).

EPA's Analysis of the State's Submittal

    The following is a summary of the major changes to Michigan's VOC 
regulations contained in the State's submittal.

I. June 1993 Submittal

    On June 12, 1993 MDNR submitted to EPA a SIP revision to address 
deficiencies in the State's ozone SIP. Listed below are descriptions of 
the changes contained in this submittal.

A. Rules 101, 103, 105, 116, 122 (Definitions A; C; E; P; V)

    Definitions have been added or revised and include the following. 
These sections have additionally been renumbered to accommodate those 
definitions which have been added or deleted.
    (1) MDNR has revised the definition of ``Actual emissions'' to not 
apply in Parts 6 and 7 of these rules. Parts 6 and 7 regulate the 
emissions of VOCs.
    (2) MDNR has removed one of the two definitions of ``Air-dried 
coating'' from the State's rules. Now there is only one definition 
which applies to all of the rules.
    (3) MDNR has revised the definition of ``Air quality standard'' to 
mean the concentration and duration of an air contaminant specified by 
the commission or by the national ambient air quality standards as 
contained in the provisions of 40 CFR part 50 (1990), whichever is more 
restrictive, as the maximum acceptable concentration and duration of 
that contaminant in the ambient air.
    (4) MDNR has added the definition of ``Calendar day'' which means a 
24-hour time period which normally is midnight to midnight, but which 
may, upon written notification to the commission, cover a different, 
consecutive 24-hour time period for a specific process.
    (5) MDNR has added the definition of ``Coating category'' which 
means a type of surface coating for which there is a separate emission 
limit specified in these rules.
    (6) MDNR has revised the definition of ``Coating line'' to mean an 
operation which is a single series in a coating process and which is 
comprised of 1 or more coating applicators and any associated flash-off 
areas, drying areas and ovens wherein 1 or more surface coatings are 
applied and subsequently dried or cured.
    (7) MDNR has revised the definition of ``Coating of fabric'' to 
include the application of coating by saturations and impregnation.
    (8) MDNR has revised the definition of ``Coating of paper'' to 
include saturation.
    (9) MDNR has revised the definition of ``Coating of vinyl'' to not 
include the application of plastisols.
    (10) MDNR has revised the definition of ``Completed organic resin'' 
to include dry organic resin.
    (11) MDNR has revised the definition of ``component'' and lists 
specific parts which are designated as ``components'' for Rules 
336.1622, 336.1628, 336.1629, and specifically excludes a valve that 
has no external controls, therefore having no potential to leak VOCs.
    (12) MDNR has added the definition of ``Extreme environmental 
conditions'' to mean any of the following: (i) Outdoor weather; (ii) 
temperatures consistently above 95 degrees celsius (203 degrees 
fahrenheit); (iii) detergents; (iv) abrasive and scouring agents; (v) 
solvents; (vi) corrosive atmospheres; (vii) other similar harsh 
conditions.
    (13) MDNR has revised the definition of ``Extreme performance 
coating'' to mean a coating which is designed to protect a coated part 
from extreme environmental conditions and which is applied to a part 
that, in its use as a finished product, is intended to be subjected to 
extreme environmental conditions.
    (14) MDNR has removed the definition of ``Pneumatic tire 
manufacturing''.
    (15) MDNR has added the definition of ``Vapor collection system'' 
which means, as it pertains to the provisions of R 336.1627, all 
piping, seals, hoses, connections, pressure-vacuum vents, and any other 
equipment between and including the delivery vessel and a stationary 
vessel, vapor processing unit, or vapor holder.
    (16) MDNR has revised the definition of ``Volatile organic 
compound'' to mean any compound of carbon or mixture of compounds of 
carbon that has a vapor pressure of more than 0.1 millimeter of mercury 
at standard conditions, excluding a number of listed compounds. The 
definition also includes compounds of carbon or mixtures of compounds 
of carbon with a vapor pressure less than or equal to 0.1 millimeter of 
mercury at standard conditions and which participates in atmospheric 
photochemical reactions.
    (17) The following definitions have undergone minor word changes 
(for example, changing the word ``which'' to ``that''): Allowable 
emissions, Coating of automobiles and light-duty trucks, Coating of 
large appliances, Component, Condenser, Contemporaneous, Creditable, 
Electrostatic prep coat, Equivalent method, Potential emissions, 
Potential to emit, Printed interior panel, Publication rotogravure 
printing, Pushside, Very large precipitator.

B. Rule 602  (General Provisions for Existing Sources of Volatile 
Organic Compound Emissions)

    MDNR has listed items which can deviate from the Part 6 regulations 
given State approval. However, in addition to needing State approval 
for any equivalent emission rate, alternate emission rate, or 
compliance method, any provision listed under 602(2) must, generally, 
be sent to EPA as a SIP revision and will not become federally 
enforceable until the SIP revision request is approved by the EPA.
    Two minor exceptions to the above provisions which do not need to 
be submitted as site-specific SIP revisions but must still have State 
approval are discussed in the Technical Support Document.6
---------------------------------------------------------------------------

    \6\The term ``Director's discretion'', as it is being used in 
this notice, is defined as a State making a decision which would be 
federally enforceable without EPA review. There are two instances in 
which Director's discretion language is being approved without need 
of U.S. EPA approval are as follows: (1) Director's discretion for 
the use of an alternate base starting level in R 336.1624(2)(a)(i) 
will be allowed because this is only applicable in areas attaining 
the ozone standard. Since these areas are not subject to RACT 
requirements Director's discretion language, in this instance, is 
allowable. (2) Director's discretion language is also acceptable for 
alternate condenser temperature in R 336.1625(4) because this 
alternate temperature will be based on the physical properties of 
chemicals passing through the condenser. These chemical properties 
are readily available in many chemistry and physics handbooks. The 
temperature at which these chemicals condense is not truly 
Director's discretion because the Director cannot influence a 
chemical's condensation temperature.
---------------------------------------------------------------------------

    In this rule the State also clarifies that for rules 336.1610, 
336.1621 and 336.1632 the phrase ``minus water'' shall also include 
compounds which are used as organic solvents and which are excluded 
from the definition of volatile organic compound. In other rules, the 
limits are based on emission rates, usually in pounds per hour, so the 
phrase ``minus water'' is only used in rules 336.1610, 336.1621 and 
336.1632 whose applicable limits are based on VOC content.

C. Rule 610  (Existing Coating Lines; Emission of Volatile Organic 
Compounds From Existing Automobile, Light-duty Truck, and Other Product 
and Material Coating Lines)

    In this rule the State sets forth the limits which shall be applied 
to the following coating line categories: automobiles and light-duty 
trucks, cons, coils, large appliances, metal furniture, magnet wire, 
and the nonmetallic surfaces of fabrics, vinyl, or paper. In addition 
to meeting the applicable emission limits, sources covered by this rule 
must also submit a written program to demonstrate compliance with the 
emission limits. Recordkeeping requirements are also contained within 
this rule. Exemptions based on, e.g., emission cutpoints (15 pounds per 
day), are listed in this rule.

D. Rule 611  (Existing Cold Cleaners)

    In this rule MDNR sets forth provisions for operating procedures 
for cold cleaners. Written procedures for compliance with these 
provisions must be developed and posted. Units that were previously 
exempt under the older version of these rules will have until 6 months 
after the date these rules become effective, in the State, to comply.

E. Rule 619  (Perchloroethylene; Emission From Existing Dry Cleaning 
Equipment)

    In this rule MDNR sets forth provisions to control the emissions of 
perchloroethylene from existing dry cleaners. In all instances, save 
one, where a comment was made by EPA on this rule, either the State 
made the change suggested by EPA or EPA withdrew the comment. Even 
though one comment has not been addressed, EPA finds this rule 
approvable. Moreover, EPA notes that it has issued a maximum available 
control technology or ``MACT'' rule for this emission source category 
with which sources will need to comply.

F. Rule 620  (Emission of Volatile Organic Compounds From Existing Flat 
Wood Paneling Coating Lines)

    The State sets forth the emission limits which shall apply to 
sources of VOC used in the coating of flat wood paneling. The State has 
replaced methods for determining VOC content in a coating with other 
recordkeeping and compliance requirements. The State has removed a 
provision allowing State discretion on equivalent emission rates and 
transfer efficiencies. The State lists exemptions to this rule. The 
State describes under what circumstances the use of an afterburner, 
used to achieve compliance with the emission limits in this rule, may 
be interrupted outside of the ozone season.

G. Rule 621  (Emission of Volatile Organic Compounds From Existing 
Metallic Surface Coating Lines)

    The State sets forth the emission limits for existing metallic 
surface coating lines and the compliance and recordkeeping requirements 
needed to demonstrate compliance with these limits. The State 
establishes an alternate limit for glass adhesion primer which is used 
to affix windshields to automobile frames. This alternate limit and its 
justification is discussed in this action's technical support document. 
The State has also replaced language providing State discretion and 
pertaining to equivalent emission rates and transfer efficiencies with 
new more explicit language which, in addition to being acceptable to 
the commission, must also receive EPA's approval before being 
incorporated into the SIP. The State lists exemptions to the provisions 
of this rule. In certain instances, the rule for coating of automobile, 
truck, and business machine parts (R 336.1632) may apply. When a source 
is complying with R 336.1632 it will not have to comply with R 
336.1622.
    In addition to these specific exemptions, the State also provides 
broader based exemptions as well. With the addition of new exemptions, 
other existing exemptions were removed from the regulations. Any 
coating lines that were previously exempt under the exemptions that 
have been removed from the rules and are no longer exempt, now have 1 
year from the State's adoption date of these rules to demonstrate 
compliance. The State has included provisions allowing the 
discontinuance of a natural gas-fired afterburner, used to meet the 
emission limits of this rule, between November 1 and March 31.

H. Rule 622  (Emission of Volatile Organic Compounds From Existing 
Components of Petroleum Refineries; Refinery Monitoring Program)

    The State has added to the list of components which require annual 
inspection those components that are ``difficult to monitor.'' The 
State has replaced the requirements for all inspections described in 
EPA 450/2-78-036 with Federal Reference Test Method 21. The State has 
defined leaking as an instance when a concentration of more than 10,000 
ppm, by volume, as methane or hexane, is measured by Method 21.
    The State has added the following provisions:
    (i) If for 2 consecutive quarters 2 percent or less of the process 
valves in a given refinery unit are found to be leaking, then 
inspections may be skipped for 1 quarter. If for 5 consecutive quarters 
2 percent or less of the process valves in a given refinery unit are 
found to be leaking, then inspections of process valves may be done 
annually. If a subsequent inspection shows that more than 2 percent of 
the process valves are leaking, quarterly inspections shall again be 
required.
    (ii) To determine the percent of valves leaking on a refinery unit, 
the total number of valves found to be leaking on the refinery unit 
during the specified monitoring period shall be divided by the number 
of valves required to be monitored.
    Under exemptions from the monitoring requirements of this rule, the 
State has removed an exemption for inaccessible valves but added an 
exemption for components that are unsafe to monitor, until monitoring 
personnel would no longer be exposed to immediate danger.
    The State has added the requirement that a current, written 
description detailing routine sampling procedures and listing the 
sealing devices involved shall be maintained and, upon request by the 
commission, shall be submitted to the commission in an acceptable 
format.

I. Rule 623  (Storage of Petroleum Liquids Having a True Vapor Pressure 
of More Than 1.0 psia, but Less Than 11.0 psia, in Existing External 
Floating Roof Stationary Vessels of More Than 40,000-gallon Capacity)

    The State has added to its list of exemptions for external floating 
roof stationary vessels, those vessels that are used to store jet 
naphtha (Jet B or JP-4).
    The State has added the requirement that any person who is 
responsible for the operation of a vessel that meets 1 of the criteria 
for exemption shall maintain records of the following:
    (i) The capacity of the stationary vessel.
    (ii) The contents of the stationary vessel.
    (iii) The type of the stationary vessel.

and may also include:

    (i) The type of primary seal.
    (ii) The true vapor pressure of the petroleum liquid.

J. Rule 624  (Emission of Volatile Organic Compounds From an Existing 
Graphic Arts Line)

    The State has rewritten much of the Graphic Arts Rule. The new rule 
sets forth the emission limits, recordkeeping requirements, compliance 
demonstration requirements and exemptions for the affected sources. 
These rules, for the most part, are written to have a statewide effect.

K. Rule 625  (Emission of Volatile Organic Compounds From Existing 
Equipment Utilized in Manufacturing Synthesized Pharmaceutical 
Products)

    The State has added a provision which describes the method for 
comparing actual emission levels from alternative control technology to 
allowable emission levels. The method for determining the actual 
emission level is found in R 336.2004 and the allowable emission level 
shall be determined using methods found in Appendix B of ``Control of 
Volatile Organic Compound Emissions From Manufacture of Pharmaceutical 
Products,'' EPA-450/2-78-029.
    The State has added language stating that a person shall not be 
required to reduce the temperature of a gas stream flowing through a 
condenser below the freezing point of a condensible component in the 
gas stream if it can be shown using intrinsic chemical data that the 
condenser would be rendered ineffective.
    The State has added a provision which describes the method for 
comparing actual emission levels from alternative control technology to 
allowable emission levels resulting from the use of a pressure/vacuum 
conservation vent. The method for determining the actual emission level 
is found in R 336.2004 and the allowable emission level shall be 
determined using methods found in Appendix B of ``Control of Volatile 
Organic Compound Emissions From Manufacture of Pharmaceutical 
Products,'' EPA-450/2-78-029.
    The State has removed the provision requiring interim reduction 
milestones since the dates of these milestones had all passed several 
years before this package was submitted.
    The State has added daily recordkeeping requirements which must be 
complied with within 3 months of the State's effective date of this 
rule. The records required shall include:
    (i) For reactors, distillation operations, crystallizers, 
centrifuges, and vacuum dryers which are controlled by a condenser or 
an alternative control technology:
    (a) A list of all VOCs in the stream.
    (b) The vapor pressure, as measured at 20 degrees Celsius, of each 
VOC.
    (c) The mole fraction of each VOC in the liquid mixture.
    (d) The gas outlet temperature of each condenser.
    (ii) For operations that are in compliance with the exemption 
provisions listed in this rule, the amount of material entering and 
exiting each reactor, distillation operation, crystallizer, centrifuge, 
and vacuum dryer.
    (iii) For air dryers, the amount of material entering and exiting 
each air dryer.
    (iv) A person loading a VOC which has a vapor pressure of more than 
210 millimeters of mercury, measured at 20 degrees Celsius, from a 
truck or railcar into an existing stationary vessel of more than a 
2,000 gallon capacity using a vapor balance system or alternate control 
system shall maintain records of the following information:
    (a) The date and time each vessel is loaded.
    (b) The type and vapor pressure, as measured at 20 degrees Celsius, 
of each VOC loaded into each stationary vessel.
    (v) For centrifuges, rotary vacuum filters, or other filters that 
have an exposed liquid surface, where the liquid contains a VOC or VOCs 
and the sum of the partial pressures is 26.2 millimeters of mercury or 
more, as measured at 20 degrees Celsius, the following records shall be 
maintained:
    (a) A list of all VOCs in the liquid.
    (b) The vapor pressure, as measured at 20 degrees Celsius, of each 
VOC.
    (c) The mole fraction of each VOC in the liquid mixture.
    (vi) For any equipment from which a liquid containing a VOC or VOCs 
can be observed dripping or running the following records shall be 
kept:
    (a) The date and time each leak was detected.
    (b) The date and time each leak was repaired.

L. Rule 627  (Delivery Vessels; Vapor Collection Systems)

    The State lists the provisions which must be met by all delivery 
vessels subject to control by a vapor collection system required by R 
336.1606, R 336.1607, R 336.1608, R 336.1609, R 336.1703, R 336.1704, R 
336.1705, or R 336.1706. The modifications made by the State to this 
rule are: (1) Listing gauge pressures in inches of water as well as in 
pounds per square inch, and (2) moving the definition of ``vapor 
collection system'' from this rule to   R 336.1122 (Definitions; V).

M. Rule 630  (Emission of Volatile Organic Compounds From Existing 
Paint Manufacturing Processes)

    The State lists the 10 moderate ozone nonattainment areas where 
these regulations shall apply. The State has removed several of the 
exemption provisions and is allowing sources which were previously 
exempt, 1 year from the rules' effective date (i.e. by April 27, 1994) 
to achieve compliance with these rules. Examples of these sources would 
be those that were not covered by the previous rules because the rules 
did not apply in that area. April 19, 1990 is the date by which other 
sources must achieve compliance.

N. Rule 631  (Emission of Volatile Organic Compounds From Existing 
Process Equipment Utilized in Manufacture of Polystyrene or Other 
Organic Resins)

    The State lists the 10 moderate ozone nonattainment areas that 
these regulations shall apply in.
    The State requires that a person shall not operate a reactor, 
thinning tank, or blending tank unless either of the following 
provisions is complied with:
    (i) All VOCs emitted from existing reactors, thinning tanks, and 
blending tanks shall be vented to control equipment that is designed 
and operated to reduce the quantity of VOCs by not less than 95 weight 
percent. Reflux condensers that are essential to the operation of the 
resin reactor are not considered to be control equipment.
    (ii) The total VOCs emitted to the atmosphere from the reactors, 
thinning tanks, and blending tanks do not exceed 0.5 pounds per 1,000 
pounds of completed organic resin produced.
    Notwithstanding the preceding requirement, the State requires the 
Monsanto Company of Trenton to comply with either of the following 
provisions for its reactors, thinning tanks, and blending tanks:
    (i) All VOCs emitted from reactors, thinning tanks, and blending 
tanks shall be vented to control equipment that is designed and 
operated to reduce the quantity of VOCs by not less than 95 weight 
percent. Reflux condensers that are essential to the operation of the 
resin reactor are not considered to be control equipment.
    (ii) The total VOCs emitted to the atmosphere from the reactors, 
thinning tanks, and blending tanks do not exceed 2.6 pounds per 1,000 
pounds of dry organic resin produced.
    The State has altered the recordkeeping requirement to now be 
mandatory for all sources subject to this rule. The recordkeeping 
requirements are effective 3 months after the effective date of this 
rule. The records which need to be kept will vary depending upon the 
fashion in which a source chooses to control the VOC emissions and may 
include any of the following information:

(i) Emissions test data.
(ii) Material balance calculations.
(iii) Process production rates.
(iv) Control equipment specifications and operating parameters.

    The State has revised one of the provisions to read,

    A person may discontinue the operation of a natural gas-fired 
afterburner, which is used to achieve compliance with the emission 
limits in this rule, between November 1 and March 31 unless the 
afterburner is used to achieve compliance with, or is required by, 
any of the following:

(a) Any other provision of these rules.
(b) A permit to install.
(c) A permit to operate.
(d) A voluntary agreement.
(e) A performance contract.
(f) A stipulation.
(g) An order of the commission.

    If the operation of a natural gas-fired afterburner is 
discontinued between November 1 and March 31 pursuant to the 
provisions of the preceding provision, both of the following shall 
apply during this time period:
    (a) All other provisions of this rule, except the emission 
limits, shall remain in effect.
    (b) All other measures that are used to comply with the emission 
limits in this rule between April 1 and October 31 shall continue to 
be used.

    A RACT analysis has been performed for the limit of 2.6 lb VOC 
emissions/1,000 pounds of dry organic resin produced set for Monsanto 
and has been found to be comparable to a RACT limit set for a similar 
Monsanto facility in Massachusetts and is therefore approvable.
    Rule 631(6) seems ambiguous as to what information is necessary to 
determine compliance because of the presence of the wording 
``information may include.'' The State has provided EPA with all of the 
compliance orders for all of the facilities affected by this rule and 
they have been reviewed to determine if sufficient information is 
included to determine compliance with this rule. EPA has found all of 
the compliance orders to contain sufficient information to determine 
compliance. All facilities are required to keep sufficient records for 
determination of compliance with this rule. Rule 702(d), described 
later in this package, requires new sources which could fall under this 
category to meet the same emission limits as existing sources in this 
category. The State has also written a letter, dated July 13, 1994, 
that clarifies the intent of this rule is to require new sources to 
meet not only the same emission limits as existing sources but also to 
meet the same recordkeeping and reporting requirements as existing 
sources as well.

O. Rule 632  (Emission of Volatile Organic Compounds From Existing 
Automobile, Truck, and Business Machine Plastic Part Coating Lines)

    The State has expanded the geographic limits of these rules to 
cover all of the moderate nonattainment counties in the State. The 
cross-line averaging provisions of this rule have been removed. 
Recordkeeping requirements have been changed to be more stringent than 
previously required.

P. Rule 702  (General Provisions for new Sources of Volatile Organic 
Compound Missions)

    The State has added a provision stating that new sources of VOCs 
shall be limited to the lowest emission rate listed in the following: 
(1) The maximum allowable emission rate listed by a commission on its 
own initiative or based upon the application of the best available 
control technology; (2) the maximum allowable emission rate specified 
by a new source performance standard promulgated by the EPA; (3) the 
maximum allowable emission rate specified as a condition of a permit to 
install or a permit to operate; or (4) the limit for this source 
category as is listed in the rules for existing sources.

Q. R 336.2004  Appendix A; Reference Test Methods; Adoption of Federal 
Reference Test Methods

    In this appendix, the State has added the following Federal 
Reference Test Methods to the list of those already adopted by 
reference:
    (1) Method 1A--Sample and velocity traverses for stationary sources 
with small stacks or ducts.
    (2) Method 2A--Direct measurement of gas volume through pipes and 
small ducts.
    (3) Method 2C--Determination of stack gas velocity and volumetric 
flow rate in small stacks and ducts (standard pitot tube).
    (4) Method 2D--Measurement of gas volumetric flow rates in small 
pipes and ducts.
    (5) Method 10B--Determination of carbon monoxide from stationary 
sources.

R. R 336.2006  Reference Test Method Serving as Alternate Version of 
Federal Reference Test Method 25 by Incorporating Byron Analysis

    The State sets forth provisions by which Federal Test Method 25 may 
be conducted by incorporating the Byron analysis.

S. R 336.2007  Alternate Version of Procedure L, Referenced in R 
336.2040(10)

    The State sets forth provisions by which an alternate version of 
the Federal Procedure L may be used.

T. R 336.2040  Method for Determination of Volatile Organic Compound 
Emissions From Coating Lines and Graphic Arts Lines

    The State sets forth provisions describing methods for determining 
compliance for coating lines in this rule. Appropriate methods are 
described for the various coating lines whose emission limits may be 
expressed differently from one another depending on the method of 
compliance being used.
    The State requires that for sources subject to emission limits 
expressed as pounds of VOCs per gallon of coating, minus water, as 
applied, the phrase ``minus water'' shall also include compounds which 
are used as organic solvents and which are excluded from the definition 
of volatile organic compound.
    For calculations required by this rule, the State requires the 
following:
    (1) Not less than 5 significant digits shall be carried in 
intermediate calculations. Rounding shall occur after final 
calculations and emission numbers will be rounded to not less than 2 
but not more than 3 significant figures.
    (2) The calculations for a coating line shall include all of the 
coatings which are in the same coating category and which are used 
during the averaging period as specified in the applicable limit.
    (3) In most cases, the calculations for a graphic arts line shall 
include all of the inks and coatings that are used during the averaging 
period as specified in the applicable emission limit.
    The State describes the methods by which the VOC content of inks 
and coatings, and the weight of VOCs used during an averaging period 
shall be determined.

U. R 336.2041  Recordkeeping Requirements for Coating Lines and Graphic 
Arts Lines

    The State sets forth the recordkeeping requirements which shall 
apply to coating lines and graphic arts lines. These provisions require 
that records for the various types of coating and graphic arts lines be 
kept.
    The types of records that must be kept are specific to the coating 
or graphic arts line and the method by which it is meeting the 
appropriate emission limit.
    All of the rules submitted for approval in the June 12, 1993 
submittal have been reviewed and found to be approvable for 
incorporation into the Michigan ozone SIP.

II. November 1993 Submittal

    On November 15, 1993 MDNR submitted to EPA a SIP revision to 
address the remaining deficiencies in the State's VOC RACT regulations 
which were not corrected by the June 12, 1993 submittal. Listed below 
are descriptions of the changes this SIP submittal proposed.

A. Rule 601  (Definitions)

    A revised definition for the term ``person responsible'' as used in 
Part 6 rules has been added.

B. Rule 602  (General Provisions for Existing Sources of Volatile 
Organic Compound Emissions)

    Provisions allowing for alternative compliance methods in Rules 628 
and 629 require site-specific SIP revisions when implemented.

C. Rule 624  (Emission of Volatile Organic Compounds From an Existing 
Graphic Arts Line)

    An unacceptable prorating method for recordkeeping has been 
removed.

D. Rule 628  (Emission of Volatile Organic Compounds From Components of 
Existing Process Equipment Used in Manufacturing Synthetic Organic 
Chemicals and Polymers; Monitoring Program) and Rule 629 (Emission of 
Volatile Organic Compounds From Components of Existing Process 
Equipment Used in Processing Natural Gas; Monitoring Program)

    Test methods have been added which define how the percent VOC in a 
piece of equipment is to be determined. Provisions allowing reduced 
frequency of monitoring for low-leaking equipment have been changed to 
comply with EPA requirements. Wording was added requiring that all 
equivalent control methods must be submitted to EPA as site-specific 
SIP revisions as specified in Rule 602. The counties affected by these 
rules have been listed in the same format as other similar rules, for 
the purpose of uniformity.

E. Non-CTG RACT Rules

    There are 3 non-CTG major sources of VOCs located in Michigan's 
Detroit-Ann Arbor ozone nonattainment area. These sources are: VCF 
Films, Inc.; Ford Motor Company's Utica Trim Plant; and the Woodbridge 
Corporations Whitmore Lake Plant (formerly Johnson Controls, Inc.). The 
course of action Michigan pursued for these companies was the 
development of administrative consent orders requiring implementation 
of RACT-level controls.
    VCF Films, Inc. has entered into an administrative consent order 
requiring RACT-level controls for VOC emissions for its film casting 
processes. This order has been submitted as a SIP revision.
    Ford Motor Company's Utica Trim Plant has entered into an 
administrative consent order requiring RACT-level controls for its 
polyurethane foam manufacturing processes, reaction injection molding 
processes, and various adhesive operations at this facility. This order 
has been submitted as a SIP revision.
    The Woodbridge Corporation, Whitmore Lake Plant (formerly Johnson 
Controls, Inc.) has entered into an administrative consent order 
requiring RACT-level controls for VOC emissions for its polyurethane 
foam automotive seat cushion manufacturing operation, and elimination 
of all methylene chloride emissions from the facility. This order has 
been submitted as a SIP revision.
    These 3 site-specific, non-CTG regulations have been reviewed by US 
EPA and are being approved for inclusion into Michigan's SIP.

F. Stage I Vapor Recovery

    Michigan has controlled VOC emissions from underground tank loading 
at service stations, called Stage I controls, since the early 1980s. 
Rule 606, the Stage I rule, currently requires services stations in the 
Detroit, Flint, Grand Rapids, and Lansing urban areas to have their 
underground gasoline storage tanks equipped with vapor balance 
equipment when unloading gasoline at the service stations.
    New Stage I legislation has recently been enacted and submitted as 
part of the November 12, 1993 submittal which expands the geographic 
coverage of the current program and lowers the exemption level. Service 
stations with greater than 10,000 gallons per month of gasoline sales 
and located in the 10 county moderate nonattainment areas will now be 
required to implement the Rule 606 Stage I controls and meet the 
equipment specifications as specified by the California Air Resources 
Board. In addition, pressure/vacuum valves on the underground storage 
tank vents will now be mandatory, as required in the equipment 
specifications.
    All of the rules submitted on November 12, 1993 have been reviewed 
and been found to be approvable by the EPA for incorporation into the 
Michigan ozone SIP.

G. Negative Declarations

    In a letter dated March 30, 1994, meant to supplement the November 
12, 1993 submittal, Michigan included current negative declarations for 
the following CTG categories: (1) Large petroleum dry cleaners; (2) 
SOCMI air oxidation processes; (3) High-density polyethylene and 
polypropylene resin manufacturing; and (4) Pneumatic rubber tire 
manufacturing. These current negative declarations obviate the need for 
Michigan to develop regulations for these source categories because 
none of these types of sources exist in the State.

Federal Action

    The EPA approves the VOC RACT rules submitted as a SIP revision for 
the State of Michigan to the EPA on June 12, 1993 and November 12, 
1993. The EPA has evaluated all of Michigan's rules, as submitted on 
June 12, 1993 and November 12, 1993 for consistency with the 
requirements of the Act, EPA regulations and the EPA's interpretation 
of these requirements as expressed in EPA policy documents. The EPA has 
found that the rules meet the requirements applicable to ozone and are, 
therefore, approvable for incorporation into the State's ozone SIP. A 
more complete discussion of the EPA's review of the State's regulations 
is contained in technical support documents dated December 11 1990, 
August 23, 1991, and May 5, 1994. The EPA is proposing to approve this 
revision as fully meeting the RACT fix-up requirements of section 
182(a)(2)(A) of the Act and the RACT catch-up requirements of section 
182(b)(2) of the Act.
    Because EPA considers this action noncontroversial and routine, we 
are approving it without prior proposal. This action will become 
effective on November 7, 1994. However, if we receive adverse comments 
by October 7, 1994, EPA will publish: (1) a document that withdraws 
this action; and (2) address the comments received in the final rule on 
the requested SIP revision which has been proposed for approval in the 
proposed rules section of this Federal Register.

Miscellaneous

A. Applicability to Future SIP Decisions

    Nothing in this action should be construed as permitting, allowing 
or establishing a precedent for any future request for revision to any 
SIP. The EPA shall consider each request for revision to the SIP in 
light of specific technical, economic, and environmental factors and in 
relation to relevant statutory and regulatory requirements.

B. Executive Order 12866

    This action has been classified as a Table 2 action by the Regional 
Administrator under the procedures published in the Federal Register on 
January 19, 1989 (54 FR 2214-2225), as revised by an October 4, 1993 
memorandum from Michael H. Shapiro, Acting Assistant Administrator for 
Air and Radiation. The OMB has exempted this regulatory action from 
E.O. 12866 review.

C. Regulatory Flexibility

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
must prepare a regulatory flexibility analysis assessing the impact of 
any proposed or final rule on small entities (5 U.S.C. 603 and 604). 
Alternatively, EPA may certify that the rule will not have a 
significant impact on a substantial number of small entities. Small 
entities include small businesses, small not-for-profit enterprises, 
and government entities with jurisdiction over populations of less than 
50,000.
    This approval does not create any new requirements. Therefore, I 
certify that this action does not have a significant impact on any 
small entities affected. Moreover, due to the nature of the Federal-
State relationship under the Act, preparation of the regulatory 
flexibility analysis would constitute Federal inquiry into the economic 
reasonableness of the State action. The Act forbids EPA to base its 
actions concerning SIPs on such grounds. Union Electric Co. v. U.S. 
E.P.A., 427 U.S. 246, 256-66 (1976).

D. Petitions for Judicial Review

    Under section 307(b)(1) of the Act, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by November 7, 1994. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this rule for the purposes of judicial review, nor does 
it extend the time within which a petition for judicial review may be 
filed and shall not postpone the effectiveness of such rule or action. 
This action may not be challenged later in proceedings to enforce its 
requirements (see section 307(b)(2)).
