DEQ seeks community participation in developing IPDES permitting and compliance user’s guide

Tuesday, January 14, 2020

BOISE — The Idaho Department of Environmental Quality (DEQ) seeks community participation in developing the Idaho Pollutant Discharge Elimination System (IPDES) User’s Guide to Permitting and Compliance: Volume 5—Storm Water General Permits, Federal Facilities, and Biosolids (User’s Guide Volume 5).

In 2018, DEQ received federal authorization to operate the IPDES program. Developing guidance documents is a key step in implementing delegated authority for this program.

The IPDES program will require entities that discharge from a point source into waters of the U.S. to submit a Notice of Intent (NOI) to DEQ (this authorization under general permits is currently approved by the U.S. Environmental Protection Agency). IPDES general permit coverage will contain limits on discharges of effluent and other provisions to protect water quality and public health.

Participants will work with DEQ staff to develop the User’s Guide Volume 5 and help the regulated community and the public understand the IPDES NOI and compliance process specific to storm water general permits (e.g., MS4, CGP, MSGP), federal facilities, and sewage sludge (e.g., biosolids).

The first meeting is scheduled for February 5, 2020, from 9 a.m. to noon at the DEQ state office (1410 N. Hilton St.).

Persons interested in participating should contact Amy Williams, IPDES rules and guidance supervisor, at (208) 373-0115 or
