Continuing Planning Process (CPP) and Antidegradation Implementation Methodology Public Participation Process

Hosted by DEQ

DEQ’s OWQ has prepared a 2020 Draft CPP and Draft Antidegradation Implementation Methodology, and will be offering them for review and comment from select stakeholders. A series of Stakeholder Meetings is planned for June and July, 2020. The public is invited to listen to the stakeholder meetings and provide written comments, but participation will be limited to the designated stakeholder representatives.

2020 Draft CPP

The Continuing Planning Process (CPP) is required by the Clean Water Act (CWA) § 303(e) [33 U.S.C. § 1313(e)], 40 C.F.R. § 130.5, and Ark. Code Ann. § 8-4-208(a). Arkansas developed and obtained approval of the CPP on January 24, 1983. Subsequent modifications were made in July 1989, November 1991, April 1993, January 1995, and June 1999.

The general purpose of the CPP is to describe the principal operational procedures of the state of Arkansas water quality management programs and permits. The U.S. Environmental Protection Agency (EPA) encourages states to review and revise their existing CPP as necessary. CPP review is not mandated in a certain timeframe. However, EPA does have authority to approve the CPP.

Draft Antidegradation Implementation Methodology

In addition to the CPP, a draft of Arkansas’ Antidegredation Implementation Methodology, as required by 40 CFR § 131.12, will also be made available for review and comment. This is the implementation methodology for Arkansas’ Antidegradation Policy in Chapter 2 of APC&EC Rule No. 2.

The Antidegradation Implementation Methodology details how the tiers of water quality protection are applied to waters and the process to allow lowering of water quality in a high quality water. This process considers a number of factors, including the classification of the waterbody, consideration of non-degrading and less degrading alternatives to the proposed activity, and comparison of economic and social benefits of the lowering of water quality proposed by the activity.
