AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Final rule.

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

SUMMARY: The USEPA is approving, in final, Ohio's 1990 base-year ozone 
precursor emissions inventories for the Canton, Cincinnati-Hamilton, 
Cleveland-Akron-Lorain and Youngstown-Warren-Sharon ozone nonattainment 
areas as revisions to the Ohio State Implementation Plan (SIP). The 
emissions inventories were submitted to satisfy a Federal requirement 
that States containing ozone nonattainment areas submit inventories of 
actual ozone precursor emissions for the year 1990. The Ohio ozone 
nonattainment areas covered by this rulemaking are Canton (Stark 
County); Cincinnati-Hamilton (Butler, Clermont, Hamilton and Warren 
Counties); Cleveland-Akron-Lorain (Ashtabula, Cuyahoga, Geauga, Lake, 
Lorain, Medina, Portage and Summit Counties); and Youngstown-Warren-
Sharon (Mahoning and Trumbull Counties).

SUPPLEMENTARY INFORMATION:

I. Background

    Section 182(a)(1) of the Clean Air Act Amendments of 1990 (Act) 
requires States with ozone nonattainment areas to submit a 
comprehensive, accurate and current inventory of actual ozone precursor 
emissions (which includes volatile organic compounds (VOC), nitrogen 
oxides (NOX), and carbon monoxide (CO)) for each ozone 
nonattainment area by November 15, 1992. This inventory must include 
anthropogenic base-year (1990) emissions from stationary point, area, 
non-road mobile, and on-road mobile sources, as well as biogenic 
(naturally occurring) sources in all ozone nonattainment areas. The 
emissions inventory must be based on conditions that exist during the 
peak ozone season (generally the period when peak hourly ozone 
concentrations occur in excess of the primary ozone National Ambient 
Air Quality Standard--NAAQS). Ohio's annual ozone season is from April 
1 to October 31 of each year.

II. Criteria for Evaluating Ozone Emissions Inventories

    Guidance for preparing and reviewing the emission inventories is 
provided in the following USEPA guidance documents or memoranda: 
``State Implementation Plans; General Preamble for the Implementation 
of Title I of the Act,'' (Preamble) as published in the April 16, 1992 
Federal Register (57 FR 13498); ``Emission Inventory Requirements for 
Ozone State Implementation Plans,'' (EPA-450/4-91-010) dated March 
1991; a memorandum from John Calcagni, Director, Air Quality Management 
Division, OAQPS, entitled ``Public Hearing Requirements for the 1990 
Base-Year Emissions Inventories for Ozone and Carbon Monoxide 
Nonattainment Areas,'' dated September 29, 1992; ``Procedures for the 
Preparation of Emissions Inventories for Carbon Monoxide and Precursors 
of Ozone, Volumes I and II,'' (EPA-450/4-91-016 and EPA-450/4-91-014) 
(Procedures; Volumes I and II) dated May 1991; and ``Procedures for 
Emissions Inventories Preparation, Volume IV: Mobile Sources,'' (EPA-
450/4-81-026d) (Procedures; Volume IV) dated 1992.
    As a primary tool for the review of the quality of emission 
inventories, the USEPA has also developed three levels (I, II, and III) 
of emission inventories checklists. The Level I and II checklists are 
used to determine that all required components of the base-year 
emission inventory and associated documentation are present. These 
reviews also evaluate the level of quality of the associated 
documentation and the data provided by the State and assess whether the 
emission estimates were developed according to the USEPA guidance. The 
Level III review evaluates crucial aspects and the overall 
acceptability of the emission inventory submittal. Failure to meet one 
of the ten critical aspects would lead to disapproval of the emissions 
inventory submittal.
    Detailed Level I and II review procedures can be found in the USEPA 
guidance document entitled ``Quality Review Guidelines for 1990 Base 
Year Emissions Inventories,'' (Quality Review) (EPA-454/R-92-007) dated 
August 1992. Level III criteria were attached to a memorandum from John 
S. Seitz, Director, Office of Air Quality Planning and Standards, 
entitled ``Emission Inventory Issue,'' dated June 24, 1993. The Level 
I, II, and III checklists used in reviewing this emissions inventory 
submittal are attached to a USEPA technical support document dated 
October 3, 1995.

III. State Submittal

    On March 15, 1994, the Ohio Environmental Protection Agency (OEPA) 
submitted a revision to the ozone portion of Ohio's SIP which consisted 
of the 1990 base-year ozone emissions inventory for the following 

[[Page 62738]]
ozone nonattainment areas in Ohio: Canton, Cincinnati-Hamilton, 
Cleveland-Akron-Lorain, Columbus, Dayton-Springfield, Toledo and 
Youngstown-Warren-Sharon. The USEPA has completed its review of the 
emissions inventories submitted for the Canton (which includes Stark 
County), Cincinnati-Hamilton (which includes Butler, Clermont, Hamilton 
and Warren Counties), Cleveland-Akron-Lorain (Ashtabula, Cuyahoga, 
Geauga, Lake, Lorain, Medina, Portage and Summit Counties) and 
Youngstown-Warren-Sharon (which includes Mahoning and Trumbull 
Counties) ozone nonattainment areas. Revisions to the March 1994 
submittal were submitted on June 8 and August 18, 1995 for these areas. 
These revisions addressed deficiencies highlighted in USEPA's proposed 
rulemaking. The 1990 base-year emissions inventories submitted for the 
Toledo and Dayton-Springfield were approved in a rulemaking published 
in the Federal Register on March 22, 1995 (60 FR 15053). The emissions 
inventory submitted for the Columbus area will be addressed in a 
separate rulemaking.

Inventory Preparation Plan/Quality Assurance Plan

    All States were required to submit an Inventory Preparation Plan 
(IPP) to USEPA for review and approval by October 1, 1991. The IPP 
documents the procedures utilized in the development of an emissions 
inventory and contains the quality assurance and quality control plan 
(QA/QC). On March 19, 1992, the State of Ohio submitted a final ozone 
emissions IPP. On April 15, 1992, USEPA informed the State that the IPP 
was not approvable at the time. Subsequently, USEPA has worked with the 
State to correct deficiencies in the IPP. With the March 1994 SIP 
revision request, the State submitted documentation of how the 
emissions inventory was prepared, as well as a quality assurance report 
for the point, area, and mobile source portions of the emissions 
inventory. The USEPA finds that this documentation and quality 
assurance report are acceptable to meet the requirements of an IPP.

Point Source Emissions Inventory

    For each nonattainment area, the State submitted a point source 
emissions inventory of all facilities that emit at least 10 tons per 
year (tpy) of VOC, or 100 tpy NOX or CO. The State also included 
sources that emit 100 tpy of VOC, CO, or NOX located in a 25-mile 
boundary surrounding each nonattainment area. The point source 
emissions inventory contains general facility information, number of 
sources, production schedules and related emissions for each source, 
emissions limitation, control efficiency and rule effectiveness (RE), 
as applicable, and total emissions on an annual and daily ozone season 
basis.
    The following methods were employed by the State to identify 
sources to be included in the 1990 base-year emissions inventory: The 
1989 records for plants in the Emissions Inventory System (EIS) were 
checked and plants meeting the VOC, CO or NOX criteria were 
revised with 1990 emissions data; the air permit records were reviewed 
for plants that are candidates for inclusion in the point source 
inventory; and current industrial directories and the Toxic Release 
Information System (TRIS) database were checked for additional point 
source emissions. For facilities in the point source inventory, the 
State acquired the emissions data by means of the following: Mail 
surveys; plant inspections; telephone calls; and air permit files.
    The USEPA reviewed the point source emissions data by cross 
referencing the point source inventory to the following sources: (1) 
USEPA's guidance document entitled ``Major CO, NO2, and VOC 
Sources in the 25-Mile Boundary Around Ozone Nonattainment Areas, 
Volume I: Classified Ozone Nonattainment Areas,'' (EPA-450/4-92-005a) 
February 1992; a 1990 TRIS Retrieval; and a 1990 Aerometric Information 
Retrieval Systems (AIRS) Facility Subsystem--Emission to Compliance 
Comparison Report.
    Where a source was governed by a regulation or a control device, 
the emissions limit was stated. A RE factor was then applied in the 
determination of emissions. In accordance with USEPA guidance, a 
standard RE factor of 80 percent was utilized, unless otherwise 
justified.

Area Source Emissions Inventory

    Area source emissions were calculated using State-specific data as 
well as USEPA guidance documents and technical memoranda developed for 
various categories. The State utilized emission factors from 
Procedures; Volumes I and IV, and AP-42 and provided necessary 
documentation. The following area source categories were included in 
the emissions inventory: Gasoline loading and distribution, dry 
cleaning, degreasing, architectural surface coatings, traffic markings, 
automobile refinishing, graphic arts, cutback asphalt, pesticide 
application, commercial/consumer solvents, bakeries, waste management 
practices (landfills), leaking underground storage tanks, incineration 
of solid waste, stationary fossil fuel combustion, and fires 
(structural, open burn, etc.). Vehicle refueling emissions were 
included as part of the mobile source emissions inventory.
    The area source inventory was reviewed utilizing USEPA's guidance 
documents, and the Level I and II checklists, to ensure that all source 
categories and their related emissions (and emission factors) were 
included in the area source emissions inventory. Seasonal adjustments, 
rule effectiveness, and rule penetration factors were applied as 
indicated in the State submittal.

On-Road Mobile Source Emissions Inventory

Development of Emission Factors
    In the development of the mobile source emissions inventory, the 
State utilized USEPA's mobile source emissions model, Mobile 5a, for 
the determination of emissions factors for eight vehicle types and 
twelve roadway types. Hard-copy documentation of the input and output 
files are provided in the State's submittal. Where available, the 
State-specific inputs were utilized in the development of the input 
files for Mobile 5a.
Development of Vehicle Miles Travelled (VMT)
    Canton, Cleveland-Akron-Lorain and Youngstown-Warren-Sharon Areas: 
The 1990 VMT for each roadway type was developed by the Ohio Department 
of Transportation (ODOT). ODOT maintains data on each section of 
highway in the State of Ohio. VMT were developed by the State Road 
Inventory System and reported through the Highway Performance 
Monitoring System (HPMS) to the Federal Highway Administration (FHWA).
    Each roadway section daily VMT (dVMT) is computed as the annual 
average daily traffic (AADT) for that section times the length of the 
section. The county DVMT is the sum of the DVMT for each highway 
functional classifications in the county. The total dVMTs are then 
summed as a statewide total. The statewide totals are then compared by 
functional class to the 1990 HPMS submittal. For those classifications 
were traffic counts are available for all or nearly all their sections, 
the totals were essentially the same. For those with more off-systems 
roads, the resulting totals were larger than the HPMS's submittal value 
(as expected). Correction factors were computed from the two sets of 
totals and applied to the individual cells. 

[[Page 62739]]

    ODOT used permanent and portable vehicle classification equipment 
to develop the vehicle mix by functional classification of highway. 
Traficomp III vehicle classification equipment are used to support the 
HPMS data collection effort. A software program called OHIO CONVERT 
formats vehicle classification data into the FHWA Vehicle 
Classification categories.
    Cincinnati-Hamilton Area: For the Cincinnati-Hamilton area, the 
Ohio-Kentucky-Indiana Regional Council of Governments (OKI) was 
responsible for the development of the mobile source emissions 
inventory. OKI developed this inventory for the Ohio and Kentucky 
portions of the interstate nonattainment area. OKI utilized the OKI 
Travel Demand Model to estimate the traffic volume on each roadway 
segment and an OKI utility program to which calculates the loaded 
speed, VMT and emissions for each roadway segment.
    The OKI travel demand model is a computerized travel demand 
forecasting model for the entire interstate nonattainment area. The 
model uses a four phase sequential travel demand forecasting process of 
trip generation, distribution modal choice and assignment. The OKI 
Travel Demand Model is composed of TRANPLAN programs and Fortran 
programs written by OKI.
    The model takes zonal demographic data and the transportation 
network as inputs and produces estimated traffic volumes on each 
roadway segment in the network. Traffic zones are the analysis units in 
the model. The OKI region is divided into 909 zones. The output of the 
model is a loaded highway network which contains information for each 
link such as initial speed, capacity, distance, functional class 
district number area type and forecasted traffic.

Off-Road Mobile Source Emissions Inventory

    Canton, Cincinnati-Hamilton and Youngstown-Warren-Sharon Areas: The 
State developed emissions estimates for the following off-road 
categories according to USEPA guidance: Aircraft, railroad locomotives, 
recreational boating, off road motorcycles, agricultural equipment, 
construction equipment, industrial equipment, and lawn and garden 
equipment. Documentation was provided as to the sources of emissions 
factors utilized and were submitted in the area source emissions 
inventory portion of the submittal.
    Cleveland-Akron-Lorain Area: The State utilized emissions estimates 
for non-road emissions developed by the Office of Mobile Sources (OMS - 
USEPA) in October 1992, in accordance with USEPA requirements for the 
Cleveland-Akron-Lorain off-road mobile source emissions inventory. 
These OMS emissions estimates are provided for off-road diesel engines, 
as well as two-stroke and four-stroke gasoline engines, including off-
road motorcycles, construction equipment, farm equipment, lawn and 
garden equipment, industrial equipment, and recreational vessels. In 
addition, the State included in the off-road mobile source inventory 
emissions from aircraft, railroads, and commercial vessels, which are 
not included in the OMS data. These estimates were developed using 
emissions factors from AP-42 and activity factors gathered from various 
sources.
    The off-road mobile source inventory was reviewed utilizing the 
Level I and II checklists and USEPA's guidance documents to ensure that 
all source categories and their related emissions factors were included 
in the off-road mobile source emissions inventory.

Biogenic Emissions Inventory

    The State of Ohio developed the naturally occurring (biogenic) 
emissions for the Canton, Cincinnati-Hamilton, Cleveland-Akron-Lorain 
and Youngstown-Warren-Sharon areas according to a USEPA's guidance 
document entitled ``User's Guide to the Personal Computer Version of 
the Biogenic Emissions Inventory System (PC-BEIS),'' (EPA-450/4-91-017) 
dated July 1991. Meteorological data utilized in PC-BEIS was collected 
in accordance with USEPA guidance. The ten warmest days from the period 
between 1988 to 1990 with the highest hourly peak ozone concentrations 
in each ozone nonattainment areas was collected and reviewed. As 
required by USEPA guidance, the corresponding ozone concentration to 
the fourth highest daily maximum temperature for each nonattainment 
area was selected and utilized in the model. The State provided hard 
copy documentation as to the meteorological inputs utilized and PC-BEIS 
output files for the biogenic emissions inventory for the Canton, 
Cincinnati-Hamilton, Cleveland-Akron-Lorain and Youngstown-Warren-
Sharon nonattainment areas.

IV. Approval of the Emissions Inventories

    In a letter addressed to Robert Hodanbosi, Chief, Division of Air 
Pollution Control, OEPA, dated March 23, 1995, USEPA provided comments 
on the 1990 base-year ozone emissions inventories submitted for the 
Canton, Cincinnati-Hamilton, Cleveland-Akron-Lorain and Youngstown-
Warren-Sharon areas. These comments addressed corrections that would be 
needed before the inventories could be finally approved.
    In a letter dated June 8, 1995, the State of Ohio provided a 
response to comments on the area, on-road and off-road mobile, and 
biogenic source emissions. The USEPA has reviewed these responses and 
finds that the State has satisfied the Agency's comments and that the 
emissions inventory for the area, on-road mobile, non-road mobile, and 
biogenic sources is approvable.
    At the time of the proposed rulemaking, the State had not responded 
to the point source emissions inventory comments that were stated in 
the March 23, 1995, letter (these comments addressed possible 
facilities that may be required to be included in the point source 
emissions inventory). The USEPA proposed to approve the State's point 
source emissions inventory contingent upon the State's response (and 
completion of USEPA's review) to the point source emissions comments.
    In a letter dated August 18, 1995, the State of Ohio provided a 
response to comments on the point source emissions inventory. The USEPA 
has reviewed these responses and finds that the State has satisfied the 
Agency's comments and that the emissions inventory for point sources is 
approvable.

V. Summary of Ozone Emissions Inventory

    The following summary indicates the emissions inventories for an 
average ozone summer weekday for the Canton, Cincinnati-Hamilton, 
Cleveland-Akron-Lorain and Youngstown-Warren-Sharon ozone nonattainment 
areas. The emissions are stated in tons per ozone season weekday:

VI. Proposed Rulemaking Action and Solicitation of Public Comment

    On July 10, 1995, USEPA published a rulemaking proposing to approve 
the emissions inventories submitted by the State of Ohio for the 
Canton, Cincinnati-Hamilton, Cleveland-Akron-Lorain, and Youngstown-
Warren-Sharon ozone nonattainment areas (refer to 60 FR 35535). No 
comments were submitted to USEPA on this proposed action. Also, the 
proposed rulemaking discussed the use of a letter notice procedure for 
final approval of this SIP revision. The USEPA has decided to take 
final action through the Federal Register and not use the letter notice 
procedure for this action.

VII. Final Action

    The USEPA is approving, in final, Ohio's 1990 base-year ozone 
precursor emissions inventories for the Canton (Stark County); 
Cincinnati-Hamilton (Butler, Clermont, Hamilton and Warren Counties); 
Cleveland-Akron-Lorain (Ashtabula, Cuyahoga, Geauga, Lake, Lorain, 
Medina, Portage and Summit Counties); and Youngstown-Warren-Sharon 
(Mahoning and Trumbull Counties) ozone nonattainment areas. These 
emissions inventories were submitted as revision to Ohio's State 
Implementation Plan.

VIII. General Provisions

    Nothing in this action should be construed as permitting, allowing 
or establishing a precedent for any future request for revision to any 
SIP. Each request for revision to any SIP shall be considered 
separately in light of specific technical, economic, and environmental 
factors and in relation to relevant statutory and regulatory 
requirements.
    This action has been classified as a Table 3 action for signature 
by the Regional Administrator under the 

[[Page 62741]]
procedures published in the Federal Register on January 19, 1989 (54 FR 
2214-2225), as revised by a July 10, 1995, memorandum from Mary 
Nichols, Acting Assistant Administrator for Air and Radiation. The 
Office of Management and Budget has exempted this regulatory action 
from Executive Order 12866 review.

IX. Regulatory Process

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., USEPA 
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, USEPA 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.
    SIP approvals under Section 110 and subchapter I, part D of the CAA 
do not create any new requirements, but simply approve requirements 
that the State is already imposing. Therefore, because the Federal SIP-
approval does not impose any new requirements, I certify that it does 
not have a significant impact on any small entities affected. Moreover, 
due to the nature of the Federal-State relationship under the CAA, 
preparation of a regulatory flexibility analysis would constitute 
Federal inquiry into the economic reasonableness of State action. The 
CAA forbids USEPA 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); 42 
U.S.C. 7410(a)(2).
    Under Sections 202, 203, and 205 of the Unfunded Mandates Reform 
Act of 1995, signed into law on March 22, 1995, USEPA must undertake 
various actions in association with proposed or final rules that 
include a Federal mandate that may result in estimated costs of $100 
million or more to the private sector, or to State, local, or tribal 
governments in the aggregate.
    Through submission of the state implementation plan or plan 
revisions approved in this action, the State has elected to adopt the 
program provided for under section 110 of the Clean Air Act. The rules 
and commitments being approved in this action may bind State, local and 
tribal governments to perform certain actions and also may ultimately 
lead to the private sector being required to perform certain duties. To 
the extent that the rules and commitments being approved by this action 
will impose or lead to the imposition of any mandate upon the State, 
local or tribal governments either as the owner or operator of a source 
or as a regulator, or would impose or lead to the imposition of any 
mandate upon the private sector, EPA's action will impose no new 
requirements; such sources are already subject to these requirements 
under State law. Accordingly, no additional costs to State, local, or 
tribal governments, or to the private sector, result from this action. 
The USEPA has also determined that this action does not include a 
mandate that may result in estimated costs or $100 million or more to 
State, local, or tribal governments in the aggregate or to the private 
sector. Approval of Ohio's emissions inventories does not impose any 
new requirements on small entities.
    Under Section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by February 5, 1996. 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).)
