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

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)

Knox County Air Quality Management (Knox County) met the timely reporting of compliance
monitoring activity minimum data requirements (MDRs), the timely reporting of stack tests and
stack test results, and the timely reporting of enforcement MDRs into ICIS-Air.

Knox County met the negotiated frequency for inspection of Title V sources and SM-80 sources,
met the goal for reviewing Title V Annual Compliance Certifications, and fulfilled the
documentation requirements for Full Compliance Evaluations (FCEs) and Compliance
Monitoring Reports (CMRs).

Knox County had formal enforcement actions that required corrective action that would return
the facility to compliance or compliance was achieved prior to the issuance of an order,
addressed HPVs in a timely manner, and took appropriate enforcement actions for HPVs. No
HPV addressing actions required Knox County to develop case development and resolution
timelines for enforcement actions requiring additional time.

Priority Issues to Address

stack test results, and the timely reporting of enforcement MDRs into ICIS-Air.

Explanation:

Data metrics 3b 1 (100%), 3b2 (100%) and 3b3 (85.7%) indicated that Knox County was timely in
reporting the compliance monitoring MDRs, the stack tests and stack test results, and the
enforcement MDRs into ICIS-Air. Knox County met the national goal and was above the national
average for these data metrics. No HPVs were identified during the review period of FY 2020 so
data metric 3a2 does not apply.

Summary:

Minor discrepancies were identified between the data in the facility files and the data that was
entered into ICIS-Air.

Explanation:

File review metric 2b indicated that 76.9% of the files reviewed reflected accurate entry of all
MDRs into ICIS-Air. Three files contained discrepancies between the information in the file and
the data that was entered into ICIS-Air. Two files contained administrative order, and the dates on
the orders in the file did not match the dates entered into ICIS-Air. A representative from Knox
County indicated that the dates listed in ICIS-Air were the dates the orders were mailed to the
facilities and not the dates the orders were issued. The other file contained a notice of violation
dated 9/9/2020. The date of the notice of violation was identified in ICIS-Air as an informal
enforcement action but the informal enforcement action was not identified as a federally reportable
violation (FRV) in ICIS-Air. A representative from Knox County indicated that the enforcement
action should have been identified as an FRV. 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.

Summary:

Knox County met the negotiated frequency for inspection of Title V sources and SM-80 sources,
met the goal for reviewing Title V Annual Compliance Certifications, and fulfilled the
documentation requirements for Full Compliance Evaluations (FCEs) and Compliance Monitoring
Reports (CMRs).

Explanation:

Data metrics 5a (100%) and 5b (100%) indicated that Knox County provided adequate inspection
coverage for Title V sources and SM-80 sources during the FY 2020 review year by ensuring that
each Title V source was inspected at least once every 2 years, and each SM-80 source was
inspected at least once every 5 years.

Data metric 5e (100%) indicated that Knox County completed the reviews of the Title V annual
compliance certifications. Knox County met the national goal and was above the national average
for these data metrics.

File review metrics 6a (100%) and 6b (100%) indicated that Knox County provided adequate
documentation of the FCE elements identified in the CAA Stationary Source Compliance
Monitoring Strategy (CMS Guidance) and provided adequate documentation in the CMRs to
determine the compliance of the facility. Knox County met the national goal for these file review
metrics.

Summary:

A minor discrepancy was identified in the accuracy of HPV/non-HPV determinations.

Explanation:

File review metric 8c indicated that 80% of FRVs reviewed showed Knox County made accurate
HPV or non-HPV determinations. One deficiency was noted because Knox County did not
accurately identify a violation as an FRV, and therefore did not determine whether the FRV would
be classified as an HPV. Incorrect information may hinder the EPA's oversight and targeting
efforts and may result in inaccurate information being released to the public. The EPA believes
that Knox County will be able to address this issue without EPA oversight.

HPVs and/or non-HPVs in a timely manner, and took appropriate enforcement actions for HPVs.
No HPV addressing actions required Knox County to develop case development and resolution
timelines for enforcement actions requiring additional time.

Explanation:

File review metrics 9a (100%), 10a (100%), and 10b (100%) indicated that Knox County was able
to return facilities to compliance, to address HPVs in a timely manner, and took appropriate
enforcement actions for HPVs. As previously noted, no HPVs were identified during the FY 2020
review year. The supplemental HPV actions from the FY 2018 review year were addressed within
the 180-day timeframe required by the HPV Policy, so Knox County did not have to develop case
development and resolution timelines and therefore, File review metric 14 does not apply. Knox
County met the national goal for these file review metrics.
