DEQ seeks comment on draft 401 water quality certification for Army Corps of Engineers Regional General Permit – Emergency

Accepting comments from July 22, 2021, through August 12, 2021.

The Idaho Department of Environmental Quality (DEQ) seeks comment on the Army Corps of Engineers Regional General Permit – Emergency. The RGP-E authorizes temporary work and/or the temporary discharge of dredged or fill material associated with emergency conditions and is restricted to those necessary during the emergency to prevent the loss of life, significant loss of property, and significant economic hardship. These activities will occur to restore, repair, and/or stabilize features that have been damaged, destroyed, or are in imminent danger of failing. Any work authorized by the RGP-E must be the minimum necessary to alleviate the immediate emergency.

Based upon its review of the Regional General Permit – Emergency (RGP-E), publicly noticed on June 11, 2021, DEQ certifies that if the permittee complies with the terms and conditions imposed by the Army Corps of Engineers permit along with the conditions set forth in this water quality certification, then it is reasonable for DEQ to conclude that the activity will comply with water quality requirements, including applicable requirements of Sections 301, 302, 303, 306, and 307 of the Clean Water Act, the Idaho Water Quality Standards (WQS) (IDAPA 58.01.02), and other appropriate water quality requirements of state law.

DEQ seeks comment on draft BNSF Railway bridge span replacement project

Accepting comments from July 7, 2021, through July 28, 2021.

The Idaho Department of Environmental Quality (DEQ) seeks comment on a draft BNSF Railway bridge span replacement project.

This project is located near the city of Sandpoint in Bonner County at the Pend Oreille Lake outlet and mouth of the Pend Oreille River. BNSF proposes repairs to the existing rail bridge over the Pend Oreille River. Pier work will involve adding bearing blocks to the top of the existing piers, and adding epoxy or cement to the existing upper portion of piers where they are degraded. The existing swing span will be replaced by two through plate girders. The project will involve concrete demolition using saws, and cast-in-place over water concrete pouring, and include extending and dismantling existing work trestle, assembling bridge spans, removing existing bridge spans, implementing pier repairs and install bearing blocks, and installing new bridge spans.

Based on its review of the 401 water quality certification request, the US Coast Guard Bridge Permit Application, and related project documents, received on May 17, 2021, DEQ certifies that if the permittee complies with the terms and conditions imposed by the permit, and the conditions set forth in this water quality certification, then it is reasonable for DEQ to conclude that the project will comply with the applicable requirements of Sections 301, 302, 303, 306, and 307 of the Clean Water Act, the “Idaho Water Quality Standards” (IDAPA 58.01.02), and other appropriate water quality requirements of state law.

DEQ seeks comment on proposed plan to lower E. coli in the Payette River Subbasin

Accepting comments from July 6, 2021, through August 6, 2021.

PAYETTE — The Idaho Department of Environmental Quality (DEQ) seeks comment on a proposed plan to address elevated levels of Escherichia coli (E. coli) in the Payette River Subbasin.

The subbasin is located in southwest Idaho and encompasses nearly 600 square miles from the western side of the West Mountains to the outlet of the Payette River and confluence with the Snake River.

The Payette River is designated for several beneficial uses, including recreation in and on the water, drinking water supply, and aquatic life support.

Under the Clean Water Act, states are required to develop total maximum daily loads (TMDLs) when state water quality standards are not achieved. To comply with these requirements, DEQ prepared the draft Payette River Subbasin Total Maximum Daily Load – Escherichia coli, which addresses primary and secondary contact recreation numeric criterion in three water bodies that act as tributaries to the Payette River.

In meeting primary and secondary contact recreation criterion, the TMDL ensures that the Payette River is further protected for recreational uses within its tributaries and downstream.

The draft plan can be accessed on DEQ’s website, at DEQ’s State Office (1410 N. Hilton Street), and at DEQ’s Boise Regional Office (1445 N Orchard St).

Written comments will be accepted through August 6, 2021, at 5 p.m. MDT. Submit comments electronically or by mail or email to:

DEQ seeks comment on revisions to stationary source air modeling guideline

Accepting comments from July 1, 2021, through August 2, 2021.

The Idaho Department of Environmental Quality (DEQ) seeks public comment on revisions to the State of Idaho Guideline for Performing Air Quality Impact Analyses (modeling guideline) that describes methods and procedures for performing air impact modeling analyses required for issuance of air quality permits.

The revision changes air pollution emission-based threshold levels that, when exceeded, trigger the requirement to perform air impact modeling analyses for facilities seeking a permit to construct (PTC) from DEQ. 

Performing air impact modeling analyses is resource-intensive for both permit applicants and DEQ. Where facilities have low air pollutant emissions, site-specific impact modeling analyses may not be necessary to conclude that applicable standards will not be violated. DEQ developed a series of thresholds to trigger when impact modeling is needed to confidently evaluate compliance with standards. These thresholds and guidance on their use are provided in Section 3 of the modeling guideline.

DEQ reevaluated the thresholds presented in the modeling guideline and revised those thresholds. A summary of DEQ’s reevaluation is presented in a technical memorandum and the new thresholds are provided in a revised Section 3 of the modeling guideline. DEQ’s revised Section 3 of the modeling guideline and the supporting technical memorandum are available for review on DEQ’s website.

Written comments on the revised modeling applicability thresholds presented in the modeling guideline will be accepted through August 2, 2021, at 5 p.m. MST. After consideration of comments received, the thresholds may be amended or adjusted in the future, in which case, DEQ may provide for additional public comment depending on the significance of the changes.

DEQ announces public comment period on draft Tier I operating permit for Avista Corporation and opportunity for public hearing

Accepting public comments from June 30, 2021, through July 30, 2021.

The Idaho Department of Environmental Quality (DEQ) seeks comment on a draft Tier I operating permit for the Avista Corporation in Rathdrum, Idaho.

The Rathdrum facility consists of two combustion gas turbine package power plants, which can each produce approximately 83.5 megawatts of electricity at full load operating conditions. The turbines operate on a simple cycle basis and are fueled exclusively by pipeline-quality natural gas.

The facility is classified as a major facility because it emits or has the potential to emit NOx and CO above the major source threshold of 100 tons-per-year and has the potential to emit over 100,000 tons-per-year CO2 equivalent of greenhouse gas pollutants. The draft permit establishes facility-wide requirements in accordance with the Idaho State Implementation Plan control strategy and the “Rules for the Control of Air Pollution” (IDAPA 58.01.01).

Comments will be accepted through July 30, 2021, at 5 p.m. MDT. Submit comments electronically on DEQ’s Public Comments page or by mail or email to:
