The results of DEP’s triennial review of West Virginia’s water quality standards have been approved by EPA.
EPA approved all but one of DEP’s submitted revisions and did not act on three items submitted.
EPA-approved changes include:
- Definition of “Cool Water Lakes” in West Virginia;
- Addition of “algae blooms” to conditions not allowable in state waters;
- Extending a half-mile rule exception on the Ohio River to mile points 61.0 to 63.5 and 70.0 to 71.0;
- Removal of the socioeconomic variance for Harmon Creek;
- Extension of the chloride variance for Davis Creek;
- Revised chronic iron criterion for trout waters to match EPA-recommended criterion; and
- Addition of “organoleptic effects” to the definition of “Category A Public Water Supply” criteria.
According to DEP, EPA took no action on three items, including a revision of the specified flow in the Monongahela River to the minimum flow regulated for navigation and a revision of the critical design flow to harmonic mean for a section of the Ohio River. The third item pertained to the minimum sample size requirements for phosphorus and chlorophyll-a sampling for lakes.
EPA did not approve the state’s weight of evidence language for applying numeric nutrient criteria to lakes.
