Allegheny County Health Dept. (ACHD) Carbon Monoxide Limited Maintenance Plan (Submitted June 2011)
Case Study #4: A Maintenance Plan and Request for Reclassification
Case Study #4: Maintenance Plan Background
• Based on CAA criteria established in 1992, EPA designated NAAs using 1988 - 89 monitor data
- In Allegheny County, the “high traffic density areas within the Central Business District (CBD) and certain other high traffic density areas” (of the Pittsburgh area) were designated “nonattainment - not classifiable”
- CBD is area enclosed by Manongahela and Allegheny rivers, and I-579
- Since the area is “not classifiable” and has CO DVs below 7.8 ppm, ACHD requested a reclassification of its CO nonattainment under provisions of the Limited Maintenance Plan Option. Further, the “not classified” designation does not require a SIP to be submittal
SIP 101 - Introduction to Air Quality Planning: Module 3 51
• CBD was designated in attainment effective January 13, 2003
- Under this reclassification, within 8 years of the designation ACHD had to submit a SIP revision to its CO Limited Maintenance Plan to ensure maintenance of the CO NAAQS for another 10 years, through 2022.
- This plan maintains existing controls and contingency provisions, and succeeds the previous plan approved by the EPA in 2003
SIP 101 - Introduction to Air Quality Planning: Module 3 52
Case Study #4: Maintenance Plan Background
• The State Maintenance Plan needs to: - include development of attainment EI to identify low enough emissions
level in the area to attain CO NAAQS • consistent with most recent EPA guidance for NAAs, and time period of monitoring
data used for maintenance demonstration • Based on actual CO emissions on “typical winter day”
- demonstrate maintenance by showing that monitored CO levels meet the NAAQS for limited maintenance areas (7.65 ppm or 85 % of CO NAAQS)
- provide for continued operation of an EPA-approved monitoring network that can verify continued attainment
- include a contingency plan to promptly correct any NAAQS violations after redesignation
- determine transportation conformity by indicating that expected emissions from planned actions are consistent with the emissions budget for the area
SIP 101 - Introduction to Air Quality Planning: Module 3 53
Case Study #4: Maintenance Plan Criteria for a Limited Area Maintenance Plan
• Dominant source of CO in CBD is on-road mobile
• Data representing “typical winter day” were produced by the Motor Vehicle Emissions Simulator (MOVES) 2010 model, recommended by EPA
Typical winter day CO emissions for Allegheny County
Page 9
III. Attainment Emissions Inventory and Mobile Source Control Measures
The dominant source of CO emissions is from on-road motor vehicles. Other contributing
sources include nonroad mobile emissions, which include lawn and garden equipment and
construction equipment, as well as area and point sources such as wood burning and cement
production. Although CO emissions are also the result of point, area, and nonroad sources, the
CO inventory only includes emissions from on-road (highway) sources, since motor vehicles are
still the primary source in the CBD. Finally, note that the data is representative of th e “ typical
winter da y,” and wa s mo deled with MO V ES20105. Table 1 illustrates the CO emissions for a
typical winter day in 2013 and Table 2 illustrates the CO emissions for a typical winter day in
2022.

As CO emissions have decreased over the last decade so have the monitored levels of CO. The
Maintenance Demonstration has graphical evidence of the decreasing CO levels since 1988.

Case Study #4: Maintenance Plan Attainment Inventory Details
Page 21
Exhibit 1: Summary of Inventory Analysis Tools
Tool Purpose
MOVES2010 Produces emission factors for CO; apply emission
factors to VMT; produce emission quantities
PPSUITE
Processes the highway data; calculates hourly
congested speeds for each state roadway segment;
prepares MOVES traffic-related input files; processes
MOVES output files and prepares summary report
CENTRAL
Provides framework to manage work tasks and
provide QA/QC features. Builds MOVES MRS files
based on user inputs and selections and executes
emission calculation process.
Exhibit 2 illustrates the analysis framework used for the inventory. PPSUITE is used to process
PennDOT traffic count data forecasted to future analysis years. The software calculates hourly congested
speeds for each roadway segment and prepares the key traffic-related inputs to MOVES. Other MOVES
input data is prepared manually. This includes inspection maintenance parameters, fuel characteristics,
vehicle age distributions, and meteorology data.
The MOVES model is executed in two steps. The first step imports the county-specific data into the
MOVES MySQL databases. MySQL is a relational database system used by MOVES. The second step
executes MOVES to estimate and apply emission factors. MOVES was run in the “inventory” mode as
described in EPA’s Technical Guidance on the Use of MOVES2010 for Emission Inventory Preparation
in State Implementation Plans and Transportation Conformity, EPA-420-B-10-023, April 2010
(http://www.epa.gov/otaq/models/moves/index.htm). The inventory mode requires input vehicle miles of
travel (VMT) and vehicle population (e.g. number of vehicles in county), which the model uses to
calculate total emission quantities for the county.
MOVES produces emissions for defined road types internal to the model. These include:
Off-Network
Rural Restricted Access (e.g. freeway)
Rural Un-Restricted Access (e.g. non-freeway)
Urban Restricted Access
Urban Un-Restricted Access
The off-network category includes emissions not associated with the travel of the vehicle. This includes
engine start emissions, resting evaporative emissions and soak emissions when a vehicle is parked. The
remaining road type categories represent the emissions associated with vehicle operation on different road
classes based on the input speeds. These emissions include running exhaust and crankcase running
exhaust emissions.
The PPSUITE software extracts the emission quantities from the MySQL databases and prepares
emission report files that can be used for tabulations.

SIP 101 - Introduction to Air Quality Planning: Module 3 56
Case Study #4: Maintenance Plan Maintenance Demonstration
• ACHD operates and maintains two stations to monitor CO according to 40 CFR Parts 53 and 58 – The monitor at Forbes Avenue and Grant Street will be
operated in accordance with 40 CFR Parts 58 to verify attainment and identify the need for contingency measures as needed
– Data from the monitors are sent to ACHD Air Quality Program computers
– The Oakland site monitor was removed from service in October 1997
– ACHD requested and was granted permission to relocate the Gateway Center Subway monitor, which had been temporarily from service in May 2000, to Flag Plaza
SIP 101 - Introduction to Air Quality Planning: Module 3 57
Case Study #4: Maintenance Plan Monitoring Network and Verification of Continuous Attainment
• Triggering Event/Indicator – Verified ambient 8-hr average CO levels > 9 ppm must be
recorded at one monitoring station at least twice within CO season (November - February)
– ACHD will review all available data, and make recommendation on contingency measure
• Contingency Measures – If the violation occurs at the Forbes Ave. monitor a vehicle
idling restriction will be implemented (only in CO season), once EPA notifies ACHD of a need for the measure, or within 3 months of the recorded violation • Vehicle idling restriction must be adopted within 12 months, and
implemented within 8 months after adoption
SIP 101 - Introduction to Air Quality Planning: Module 3 58
Case Study #4: Maintenance Plan Contingency Plan
• Alternative Contingency Measures
– ACHD reserves the right to petition EPA on the use of alternatives to the vehicle idling restriction if such measures (or combinations of measures) can be demonstrated to EPA’s satisfaction of being equally, or more beneficial to air quality and public health compared to the vehicle idling restriction

• Civil liability arises simply through the existence of a violation; no requirement for prior knowledge or intent
• Civil Administrative Actions: notice of violation or an order (with our without penalties) directing an entity to take action to come into compliance
• Civil Judicial Actions: court filing against entities that have failed to comply with statutory/regulatory requirements or comply with an administrative order
Enforcement Civil Actions
65 SIP 101 - Introduction to Air Quality Planning: Module 3
• Possible Outcomes: – Settlements may include consent agreements/final orders,
administrative orders on consent, or consent decrees
– Penalties are designed to recover the economic benefit of noncompliance and to compensate for the seriousness of the violation
– Injunctive Relief forces a regulated entity to perform or refrain from performing some designated action
– Supplemental Environmental Projects are environmental improvement projects that violators voluntarily agree to perform
Enforcement Civil Actions
66 SIP 101 - Introduction to Air Quality Planning: Module 3
• Criminal liability is triggered through a demonstration of intent to violate NAAQS
• Reserved for the most egregious violations that are willful or knowingly committed
• Possible Outcomes: – Criminal Penalties are fines imposed by a Judge at
sentencing; may include restitution to those affected by the violation
– Incarceration
Enforcement Criminal Actions

SIP Challenges
Reference(s)
• APTI, SIP Law & Rulemaking on State Implementation Plans
• CAA includes provisions that allow citizens to sue EPA when EPA fails to perform an act or duty required by the statute
– CAA was the first environmental law in the U.S. to allow citizen suits
• Plaintiffs must provide the EPA with a Notice of Intent (NOI) to sue in advance of a lawsuit
SIP Challenges Citizen Suits
73 SIP 101 - Introduction to Air Quality Planning: Module 3
SIP Challenges Citizen Suits
• Under U.S. Code Title 42 § 7604 (Section 304 of the CAA), citizens may sue: – Any person, including the U.S. government, or
other governmental agency for violating emission standards
– EPA Administrator for failing to perform any nondiscretionary act or duty under the CAA
– Entities proposing to construct new or modified facilities without the proper permits
74 SIP 101 - Introduction to Air Quality Planning: Module 3
SIP Challenges Citizen Suits
• Requirements
– Citizens must be adversely impacted by violation
– Violators, State, and EPA must have a 60-day notice of the alleged violation
• Violators may use the 60-day period to correct and give EPA or State an opportunity to enforce compliance
75 SIP 101 - Introduction to Air Quality Planning: Module 3
SIP Challenges Citizen Suits
• CAA 304(a)(1) may be used to enforce standards and limits in the current SIP, even if there is a pending SIP revision submitted to EPA
• CAA 304(a)(2) confers citizen suit authority to compel EPA to make findings and promulgate a FIP for SIP revisions that have not been submitted
76 SIP 101 - Introduction to Air Quality Planning: Module 3
• If EPA acts on a SIP revision, the EPA rulemaking is subject to challenge under the Administrative Procedure Act (APA) as a final action – Tried in a Federal Court of Appeals
• If EPA fails to act on a SIP revision within 12 months of completeness determination or if a rule is challenged as unlawful then EPA is subject to lawsuit – Tried in Federal District Court
SIP Challenges Lawsuits
77 SIP 101 - Introduction to Air Quality Planning: Module 3
• Court Options
– Vacate and Remand: Rule or plan is no longer in effect
– Remand without Vacating: Rule or plan remains in effect but EPA will need either to re-propose or recommence final action
– Remand with Partial Vacate: If possible, remove the defective part of the rule or plan
– Uphold: Permit the rule or plan to remain in effect as promulgated
SIP Challenges Lawsuits
78 SIP 101 - Introduction to Air Quality Planning: Module 3
What happens if a State misses a SIP deadline?
• Sanctions! – Discretionary Sanctions, CAA 110(m) – Mandatory Sanctions, CAA 179
• Sanctions triggered by: – Finding of failure to submit a complete SIP – Finding of failure to implement any element of an
approved SIP – Disapproval of a SIP – Failure to submit a SIP revision for which EPA has
issued a SIP call or disapproval notice
79 SIP 101 - Introduction to Air Quality Planning: Module 3
Sanctions
• Mandatory, CAA §179 – 2:1 Offsets = A ratio of at least 2:1 emissions reductions within
the NAA for new or modified major facilities undergoing NSR; may be statewide in transport regions
– Highway = Funding moratorium for all but exempt projects (safety, mass transit)
• Discretionary, CAA §110(m) – Applies to all SIP elements (NAA and non-Part D) – May be applied “at any time” after trigger, meaning EPA has the
discretionary authority to shorten the 18/24 month clocks – Offset sanctions only apply to where NAA, NSR requirements
apply – Highway sanctions may apply anywhere (NAA or non-NAA)
80 SIP 101 - Introduction to Air Quality Planning: Module 3
Sanctions
• Sanctions Clock – After 18 months: 2-for-1 NAA offset requirement
under NSR
– After 24 months: Highway sanctions
• FIP Clock – EPA has 24 months to promulgate a FIP
• Clocks start with publication of EPA notice in the Federal Register: Finding of failure to submit SIP, Disapproval of SIP, or Failure to implement SIP
81 SIP 101 - Introduction to Air Quality Planning: Module 3
Sanctions
• Offset sanctions only apply within NAAs where the SIP or SIP element associated with the finding of failure or disapproval applies
• Highway sanctions may apply in both NAA and attainment areas
• Sanctions are not triggered if an area fails to attain NAQQS on time (i.e. an approved SIP did not work)
82 SIP 101 - Introduction to Air Quality Planning: Module 3
Sanctions Stopping the Clocks
• Before 18 months – Interim Final Determination (IFD) – EPA determines
that the SIP deficiency is corrected and sanctions are deferred pending EPA final action on the corrected SIP
• 18-24 months – IFD will stay 2-for-1 offsets and defer highway
sanctions
• After 24 months – IFD will stay both sanctions
83 SIP 101 - Introduction to Air Quality Planning: Module 3
Sanctions Stopping the Clocks: EPA Actions
• From a Failure to submit – EPA final action is a letter to the Governor that the
submitted SIP is complete and it corrects the deficiencies
• From a SIP Disapproval – EPA final action is final rulemaking to approve the SIP
that is now complete and corrected
• From a Failure to Implement – EPA final action is a Federal Register notice that the
State is implementing the SIP
84 SIP 101 - Introduction to Air Quality Planning: Module 3
Federal Implementation Plans (FIPs)
• 24 months after EPA disapproves or makes a finding of failure to submit a required plan, it has nondiscretionary duty to promulgate a FIP
• The FIP should correct the SIP deficiency; no more and no less
• Clock is turned off only after EPA approves a SIP revision
85 SIP 101 - Introduction to Air Quality Planning: Module 3
Conformity Implications of SIP Disapprovals
• ROP and attainment plans include mobile source budgets (MVEB) for NAAs
• Disapproval of either control strategy plans has Transportation Conformity Implications
– Conformity Freeze
– Conformity Lapse
86 SIP 101 - Introduction to Air Quality Planning: Module 3
Conformity Implications Conformity Freeze
• If a control strategy SIP (ROP or MVEB) is disapproved, only projects within 1st 4 years of current transportation plan can be funded and continue forward
• A new SIP revision with adequate controls must be approved to allow the conformity plan to proceed
• Conformity freezes are effective immediately upon the effective date of the disapproval; not 18 or 24 months later
87 SIP 101 - Introduction to Air Quality Planning: Module 3
Conformity Implications Conformity Lapse
• Once highway sanctions have been imposed, no new transportation improvement program (TIP), transportation plan, or project can be funded or found to conform until a new SIP is submitted.
• A new TIP or transportation plan cannot be approved until the mobile budgets in the new SIP are found adequate and approved by EPA
88 SIP 101 - Introduction to Air Quality Planning: Module 3
Conformity Implications Conformity Lapse
• Protective Finding: prevents the freeze (but not the lapse) if the disapproved SIP contained enforceable measures to achieve all required emissions reductions
89 SIP 101 - Introduction to Air Quality Planning: Module 3
SIP Calls
• If EPA finds an approved SIP is substantially inadequate to attain or maintain NAAQS or otherwise comply with CAA – EPA may call on a State to revise its SIP to correct
the deficiencies by a given due date
– If not submitted by the due date or the “called” revision is disapproved, the State is subject to sanctions
• NOx SIP Call Example
90 SIP 101 - Introduction to Air Quality Planning: Module 3
NOx SIP Call of 1998
• Purpose: Reduce regional transport of ozone • Applied to 22 Eastern U.S. States and District of
Columbia • Required SIP revisions to reduce NOx emissions
from large stationary sources by May 2003 • Developed by the Ozone Transport Assessment
Group: partnership between EPA, States, industry, and environmental groups
• Resulted in a NOx emissions trading program among participating States
