Section 611.160  Composite Correction Program

a)         The Agency may issue a SEP requiring a PWS to conduct a Composite Correction Program (CCP).  The CCP must consist of two elements:  a Comprehensive Performance Evaluation (CPE) and a Comprehensive Technical Assistance (CTA).

1)         A CPE is a thorough review and analysis of a plant's performance-based capabilities and associated administrative, operation, and maintenance practices.  The CPE must identify factors that may adversely affect the plant's ability to comply and emphasize approaches the PWS can implement without significant capital improvements.

2)         For purposes of compliance with Subparts R and X, the CPE must minimally include specific components:  the CPE must assess plant performance; evaluate major unit processes; identify and prioritize performance-limiting factors; assess the applicability of comprehensive technical assistance; and how the PWS prepared CPE report.

BOARD NOTE:  This subsection (a)(2) derives from the third sentence of the definition of "comprehensive performance evaluation" in 40 CFR 141.2.

3)         A CTA is the performance-improvement phase the PWS implements if the CPE results indicate potential for improved performance.  During the CTA phase, the PWS must identify and systematically address plant-specific factors.  The CTA is a combination of utilizing CPE results as a basis for followup, implementing process control priority-setting techniques, and maintaining long-term involvement to systematically train staff and administrators.

b)         A PWS must implement any follow-up recommendations the Agency makes in writing as a result of the CCP.

c)         A PWS may appeal to the Board, under Section 40 of the Act, any Agency requirement that it conduct a CCP or any follow-up recommendations the Agency makes in writing as a result of the CCP, except when a CPE is required under Section 611.745(b)(4).

BOARD NOTE:  This Section derives from 40 CFR 142.16(g).
