Composite Correction Program (Ccp)

40 CFR 141.563 is incorporated by reference. In accordance with 40 CFR 142.16(g)(1), the Department has authority to require the owner of a PWC to conduct a composite correction program, as defined in Section 003, for the purpose of identifying and correcting deficiencies in water treatment and distribution. Composite Correction Programs consis t of a Comprehensive Performance Evaluation (CPE) and Comprehensive Technical Assistance (CTA). (7-1-24) 01. Comprehensive Performance Evaluation (CPE). The CPE is conducted to identify factors tha t may be adversely impacting a plant’s capability to achieve compliance. It must emphasize approaches that can be implemented without significant capital improvements. The CPE assesses plant performance-based capabilities an d associated administrative and operation and management practices. (7-1-24) 02. Comprehensive Technical Assistance (CTA). The CTA consists of follow-up to the CPE results, implementation of process control priority setting techniques, and long-term involvement to systematically train staff and administrators.

COLIFORM TREATMENT TECHNIQUE TRIGGERS AND ASSESSMENT REQUIREMENTS FOR PROTECTION AGAINST POTENTIAL FECAL CONTAMINATION. 40 CFR 141.859, excluding 40 CFR 141.859(a)(2)(iii), is incorporated by reference. (7-1-24) 01. Requirements For Assessments. 40 CFR 141.859(b) is incorporated by reference. (7-1-24) a. Level 1 and 2 assessments must be conducted consistent with any Department directives that tailo r specific assessment elements with respect to the size and type of the PWS and the size, type, and characteristics of th e distribution system. (7-1-24) b. Level 1 Assessment. 40 CFR 141.859(b)(3) is incorporated by reference. (7-1-24) c. Level 2 Assessment. 40 CFR 141.859(b)(4) is incorporated by reference. (7-1-24) i. The Department will schedule and conduct Level 2 assessments for an E.coli treatment technique trigger in unless the Department approves another party to conduct the assessment as outlined in Subsection 305.02. (7-1-24) ii. A second or any additional triggered Level 2 Assessment within a rolling twelve-month perio d must be conducted by a Department approved third party even if the PWS owner has staff or management approved under Subsection 305.02. (7-1-24) 02. Approved Parties for Level 2 Assessments. The PWS may conduct a Level 2 assessment if the PWS has staff or management with the certification or qualifications outlined in this Subsection or if the PWS hire s parties that meet the qualifications in this Subsection. The following parties are approved by the Department to conduct Level 2 assessments: (7-1-24) a. The Department or persons contracted with the Department who are trained to conduct sanitar y surveys; (7-1-24) b. Currently licensed operators in good standing that are licensed through the Idaho Division o f Occupational and Professional Licenses with a drinking water classification of Distribution I through IV or Treatment I through IV and that are licensed at least to the classification level of the PWS requiring the Level 2 assessment; or (7-1-24) c. Licensed professional engineers licensed by the state of Idaho and qualified by education and experience in the specific technical fields involved in these rules. (7-1-24) 306. -- 309. (RESERVED) 310. ENHANCED FILTRATION AND DISINFECTION - SYSTEMS SERVING FEWER THAN TEN THOUSAND PEOPLE. 40 CFR 141, Subpart T, is incorporated by reference. (7-1-24) 311. ENHANCED TREATMENT FOR CRYPTOSPORIDIUM -- LONG TERM 2 ENHANCED SURFACE WATER TREATMENT RULE. 40 CFR Part 141, Subpart W, is incorporated by reference. (7-1-24) 01. Cryptosporidium Treatment Credit for Approved Watershed Control Program. Th e Department will award 0.5 (zero point five) logs cryptosporidium removal credit to systems that have a Departmen t approved Watershed Control Program. Requirements for a watershed control program are set forth in 40 CFR 141, Subpart W. Guidance on how to develop a watershed control program and obtain Department approval is provided i n “Implementation Guidance for the Long Term 2 Enhanced Surface Water Treatment Rule,” as referenced in Sectio n 002. (7-1-24) 02. Assessment of Significant Changes in the Watershed. As part of the sanitary survey process se t forth in Section 302, the Department, or an agent approved by the Department, will assess significant changes in th e watershed of a surface water system that occurred since the PWS conducted source water monitoring. If changes i n the watershed have the potential to significantly increase contamination of the source water with cryptosporidium, th e Department will consult with the PWS owner on follow-up actions that may be required under 40 CFR 141, Subpar t W, including, but not limited to, source water monitoring or additional treatment requirements. “Implementation Guidance for the Long Term 2 Enhanced Surface Water Treatment Rule,” as referenced in Section 002, provides a description of factors that will be considered by the Department when making an assessment of changes in th e watershed. These factors include, but are not limited to the following: (7-1-24) a. New IPDES permits or changes in existing IPDES permits that involve increased loading of contaminants. (7-1-24) b. Changes in land use patterns. (7-1-24) c. Changes in agricultural cropping, chemical application, or irrigation practices. (7-1-24) d. Changes in other non-point discharge source activities (such as grazing, manure application, commercial or residential development). (7-1-24) e. Stream or riverbed modifications. (7-1-24) f. IPDES permit violations at wastewater treatment plants or confined animal feedlot operations. (7-1-24) g. Dramatic natural events such as floods, forest fires, earthquakes, and landslides that may transpor t or expose contaminants. (7-1-24) h. Prolonged drought conditions that may warrant special preparatory measures to minimize impact s from waste accumulations that are washed into source waters when precipitation returns. (7-1-24) i. Accidental or illegal waste discharges and spills. (7-1-24) 312. -- 319. (RESERVED) 320. DISINFECTANT RESIDUALS, DISINFECTION BYPRODUCTS, AND DISINFECTION BYPRODUCT PRECURSORS.
