I. Introduction

A.	Overview of the State Review Framework

The State Review Framework (SRF) is a key mechanism for EPA oversight, providing a
nationally consistent process for reviewing the performance of state delegated compliance and
enforcement programs under three core federal statutes: Clean Air Act, Clean Water Act, and
Resource Conservation and Recovery Act. Through SRF, EPA periodically reviews such
programs using a standardized set of metrics to evaluate their performance against performance
standards laid out in federal statute, EPA regulations, policy, and guidance. When states do not
achieve standards, the EPA will work with them to improve performance.

Established in 2004, the review was developed jointly by EPA and Environmental Council of the
States (ECOS) in response to calls both inside and outside the agency for improved, more
consistent oversight of state delegated programs. The goals of the review that were agreed upon
at its formation remain relevant and unchanged today:

1.	Ensure delegated and EPA-run programs meet federal policy and baseline performance
standards

2.	Promote fair and consistent enforcement necessary to protect human health and the
environment

3.	Promote equitable treatment and level interstate playing field for business

4.	Provide transparency with publicly available data and reports

B.	The Review Process

The review is conducted on a rolling five-year cycle such that all programs are reviewed
approximately once every five years. The EPA evaluates programs on a one-year period of
performance, typically the one-year prior to review, using a standard set of metrics to make
findings on performance in five areas (elements) around which the report is organized: data,
inspections, violations, enforcement, and penalties. Wherever program performance is found to
deviate significantly from federal policy or standards, the EPA will issue recommendations for
corrective action which are monitored by EPA until completed and program performance
improves.

The SRF is currently in its 4th Round (FY2018-2022) of reviews, preceded by Round 3
(FY2012-2017), Round 2 (2008-2011), and Round 1 (FY2004-2007). Additional information
and final reports can be found at the EPA website under State Review Framework.

II. Navigating the Report

The final report contains the results and relevant information from the review including EPA and
program contact information, metric values, performance findings and explanations, program
responses, and EPA recommendations for corrective action where any significant deficiencies in
performance were found.

-------
A.	Metrics

There are two general types of metrics used to assess program performance. The first are data
metrics, which reflect verified inspection and enforcement data from the national data systems
of each media, or statute. The second, and generally more significant, are file metrics, which are
derived from the review of individual facility files in order to determine if the program is
performing their compliance and enforcement responsibilities adequately.

Other information considered by EPA to make performance findings in addition to the metrics
includes results from previous SRF reviews, data metrics from the years in-between reviews,
multi-year metric trends.

B.	Performance Findings

The EPA makes findings on performance in five program areas:

•	Data - completeness, accuracy, and timeliness of data entry into national data systems

•	Inspections - meeting inspection and coverage commitments, inspection report quality,
and report timeliness

•	Violations - identification of violations, accuracy of compliance determinations, and
determination of significant noncompliance (SNC) or high priority violators (HPV)

•	Enforcement - timeliness and appropriateness of enforcement, returning facilities to
compliance

•	Penalties - calculation including gravity and economic benefit components, assessment,
and collection

Though performance generally varies across a spectrum, for the purposes of conducting a
standardized review, SRF categorizes performance into three findings levels:

Meets or Exceeds: No issues are found. Base standards of performance are met or exceeded.

Area for Attention: Minor issues are found. One or more metrics indicates performance
issues related to quality, process, or policy. The implementing agency is considered able to
correct the issue without additional EPA oversight.

Area for Improvement: Significant issues are found. One or more metrics indicates routine
and/or widespread performance issues related to quality, process, or policy. A
recommendation for corrective action is issued which contains specific actions and schedule
for completion. The EPA monitors implementation until completion.

C.	Recommendations for Corrective Action

Whenever the EPA makes a finding on performance of Area for Improvement, the EPA will
include a recommendation for corrective action, or recommendation, in the report. The purpose
of recommendations are to address significant performance issues and bring program
performance back in line with federal policy and standards. All recommendations should include

3


-------
specific actions and a schedule for completion, and their implementation is monitored by the
EPA until completion.

Executive Summary

Areas of Strong Performance

The following are aspects of the program that, according to the review, are being implemented at
a high level:

Clean Air Act (CAA)

The Nashville/Davidson County, Tennessee, Metro Public Health Department Air Pollution
Control Division (MPHD) was timely in the reporting of high priority violations (HPVs), and
timely in the reporting of enforcement minimum data requirements (MDRs) in ICIS-Air.

MPHD met the negotiated frequency for inspection of Title V sources and SM-80 sources,
completed the reviews of the Title V Annual Compliance Certifications, provided the necessary
documentation for Full Compliance Evaluations (FCEs), and provided the necessary
documentation for the Compliance Monitoring Reports (CMRs).

MPHD was timely in identifying HPVs.

MPHD issued formal enforcement actions that returned facilities to compliance, addressed HPVs
in a timely manner, and appropriately addressed HPVs consistent with the HPV Policy.

Priority Issues to Address

The following are aspects of the program that, according to the review, are not meeting federal
standards and should be prioritized for management attention:

Clean Air Act (CAA)

Discrepancies were identified between the information in the facility files and the data that was
entered in ICIS-Air. In addition, MPHD did not meet the timely report of the minimum data
requirements (MDR) for stack tests and stack test results into ICIS-Air.

Explanation:

Data metric 3b 1 (77.9%) indicated that MPHD was timely in the reporting of 88 out of 113
compliance monitoring MDRs in ICIS-Air. Of the 25 late compliance monitoring MDRs entries
in ICIS-Air, 22 were associated with late entry of full compliance evaluations, and the remaining
three were associated with late entry of title V annual compliance certifications. To address the
late data entries associated with the FCEs, MPHD indicated that they will evaluate the items
outlined in the CMS policy for FCEs from the date of the onsite inspection and the previous 12
months.

State Response:

Since the CMS Policy assigns FCEs to a specific fiscal year, APC was under the impression that
the FCE was the summation of all enforcement activities (inventory, periodic reports, on-site
inspection, etc.) from that fiscal year. Through this process we learned that EPA defines the FCE
as all enforcement activities that take place in the 12 months prior to the on-site inspection. The
22 late entries for full compliance evaluations are due to APC waiting for a piece of information
relevant to the specific fiscal year, despite the on-site inspection having already been conducted.
In the future, APC will follow EPA's methodology and report the FCE date as the date of the on-
site inspection.

Area for Improvement

Recurring Issue:

Recurring from Round 3

Summary:

Discrepancies were identified between the information in the facility files and the data that was
entered in ICIS-Air. In addition, MPHD did not meet the timely reporting of the minimum data
requirements (MDR) for stack tests and stack test results into ICIS-Air.

Explanation:

File review metric 2b indicated that 52.6% of the files reviewed reflected accurate entry of all
MDRs in ICIS-Air. Nine files contained discrepancies between the information in the file and the
data that was entered in ICIS-Air. The discrepancies consisted of air programs and subparts not
being identified in ICIS-Air, inaccurate dates associated with Title V annual compliance
certifications in ICIS-Air, inaccurate full compliance evaluation information in ICIS-Air, informal
enforcement action information not being entered in ICIS-Air, and federally reportable violation
information not being entered in ICIS-Air. A representative from MPHD confirmed the
discrepancies that were identified during the file review. Incorrect data has the potential to hinder
the EPA's oversight and targeting efforts and may result in inaccurate information being released
to the public. Data metric 3b2 (50%) indicated that MPHD was timely in reporting of one of the
two stack tests and stack results into ICIS-Air. A representative from MPHD indicated that the
discrepancy was due to an oversight.

State Response:

2b - The mismatch in dates is due to the documents being stamped when they enter the building.
Our ICIS Coordinator was recording the dates that he had received and reviewed the document.
This discrepancy will be corrected. There were also several cases where a source was missing a
NESHAP or NSPS listing. These were rules that came into effect after the sources were entered

into ICIS. These corrections have been made and Nashville will be watching for additional
regulations in the future.

3b2 - The ICIS Coordinator entered the date of the test when it occurred. He forgot to update ICIS
once the final report was received. This will be corrected moving forward.

Recommendation:

Summary:

Discrepancies were identified in the accuracy of high priority violation (HPV) determinations.
Explanation:

File review metric 8c (40%) indicated that two of the five files reviewed had accurate HPV
determinations. The three discrepancies consisted of MPHD issuing notices of violation that were
not identified as federally reportable violations and therefore an HPV determination was not made.

resolved.

Recommendation

File metric 8c: By May 1, 2023, MPHD will provide to the EPA a
written description of the root causes for the inaccurate HPV
determinations, and a written description of what measures and/or
procedures have been implemented to ensure accurate HPV
determinations are made. By December 29, 2023, the EPA will review
a random selection of facility files that contain informal enforcement
actions and evaluate file metric 8c to ensure HPV determinations have
improved. Once file metric 8c indicates a 71.0% or greater of HPV
determinations, then this recommendation will be considered complete.

CAA Element 4 - Enforcement

Finding 4-1

Meets or Exceeds Expectations

Recurring Issue:

No

Summary:

MPHD issued formal enforcement actions that returned facilities to compliance, addressed HPVs
in a timely manner, and appropriately addressed HPVs consistent with the HPV Policy.

Explanation:

File review metrics 9a (100%), 10a (100%), and 10b (100%) indicated that MPHD returned
facilities to compliance, addressed HPVs in a timely manner, and appropriately addressed HPVs
consistent with the HPV policy. All HPV actions were addressed within the 180-day timeframe
required by the HPV Policy, so MPHD did not have to develop case development and resolution
timelines and therefore, file review metric 14 does not apply.

CAA Element 5 - Penalties

Finding 5-1

Area for Attention

Recurring Issue:

No

Summary:

MPHD did not assess civil penalties during the review period of FY 2021.

Explanation:

MPHD did not assess civil penalties for any Title V sources, SM-80 sources or sources included
in the CMS plan during the FY 2021 review year, so the EPA was unable to evaluate penalty
calculations and penalty collection documentation (File Review Metrics 11a, 12a and 12b). The
EPA addresses such anomalous cases by reviewing activities from previous reporting periods.
However, the EPA has determined that there were no civil penalties assessed for any Title V
sources, SM-80 sources or sources included in the CMS plan during FY 2015 thru FY 2020. As a
result, the EPA is recommending that this element be considered an Area of Attention, and that
MPHD conduct an assessment to determine if corrective action procedures are warranted.

State Response:

This finding is not entirely accurate, but EPA could have drawn no other conclusions. Nashville
does collect penalties, but most of them don't go through our enforcement staff, which may explain
why they weren't being reported. It is very rare for us to have an "environmental violation" where
our staff inspects a facility and finds a violation causing environmental harm. The majority of our
penalties are "administrative" in nature. These would include late fees, late reports, minor sources
not getting a timely construction permit, etc. These are mostly handled in bulk by our clerical staff.
A list of penalties assessed in 2021 has been included for your review. Going forward, these will
be included in the ICIS system.
