UPDATED: DEQ extends comment period for draft Jordan Creek Mercury Total Maximum Daily Load
Accepting comments from March 27, 2025, through June 11, 2025.
The Idaho Department of Environmental Quality (DEQ) is extending the public comment period for the draft Jordan Creek Mercury Total Maximum Daily Load.
The initial public comment period was set to end on April 27, 2025. The public now has until June 11, 2025, to submit comments.
The total maximum daily load (TMDL) sets mercury load limits for five impaired assessment units (i.e., the portions of a stream between two tributary intersections) in the Jordan Creek subbasin. These segments are designated as impaired on Idaho’s 303(d) list in the 2024 Integrated Report.
The Jordan Creek subbasin spans from southwestern Idaho into southeastern Oregon. Historic mining practices led to elevated mercury levels in parts of the system. Under the Clean Water Act, states are required to develop TMDLs when state water quality standards are not achieved. To comply with these requirements, DEQ prepared the draft Jordan Creek Mercury Total Maximum Daily Load, which establishes water quality targets and load capacities, estimates existing pollutant loads, and allocates responsibility for load reductions needed to return listed waters to a condition meeting Idaho’s water quality standards. The draft TMDL document was developed in consultation with the Jordan Creek Watershed Advisory Group.
The draft TMDL is available for review on DEQ’s Public Comment Opportunities web page and at DEQ’s State Office (1410 North Hilton Street, Boise, Idaho 83706). Written comments will be accepted through June 11, 2025, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:

DEQ recommends EPA designate all Idaho airsheds as meeting new particulate matter standards
February 4, 2025
Contact: Mary Anderson, Air Quality Bureau Chief, Mary.Anderson@deq.idaho.gov
BOISE – The Idaho Department of Environmental Quality (DEQ) recommends that the U. S. Environmental Protection Agency (EPA) designate all Idaho airsheds as meeting new federal health standards for particulate matter (PM2.5).
In 2024, EPA lowered the annual health-based National Ambient Air Quality Standards for PM2.5 from 12 µg/m3 to 9 µg/m3. Particulate matter are microscopic particles emitted from sources like wildfires, outdoor burning, woodstoves, and vehicles. These particles can penetrate deep into the lungs and enter the bloodstream, increasing the risk of heart disease, lung cancer, stroke, and other health conditions, especially for vulnerable groups.
DEQ is recommending that EPA exclude wildfire smoke impacts that contribute to days with high PM2.5 concentrations, which would keep Idaho airsheds within the new national levels. Some wildfire events are considered “exceptional” and not representative of typical air quality conditions. EPA will review DEQ’s recommendation and finalize designations for Idaho based on the most recent data, most likely 2022-2024, by February 7, 2026.
DEQ’s recommendation comes after Idaho communities have worked for years to improve air quality, including replacing old woodstoves, providing woodsheds and moisture meters to homeowners, and much more.
DEQ’s recommendation letter is available here.

DEQ finalizes use attainability analysis for Bucktail Creek
November 26, 2024
Contact: India Southern, Water Quality Standards Analyst, India.Southern@deq.idaho.gov
BOISE – The Idaho Department of Environmental Quality (DEQ) today published the final use attainability analysis (UAA) for Bucktail Creek, recommending no change in beneficial use designations.
Bucktail Creek is a small stream draining on the north side of the Blackbird Mine in Lemhi County, Idaho. Early mining operations resulted in contaminated mine drainage in Bucktail Creek and surrounding water bodies, leading to extensive water quality restoration efforts.
DEQ first published a UAA for Bucktail Creek in 2002 in order to assess the physical, chemical, and biological characteristics of the water body and determine the appropriate beneficial use designations (i.e., recreation, water supply, aquatic life, agriculture, etc.). In that analysis, DEQ examined the designated beneficial uses for Bucktail Creek and determined that it could not support aquatic life due to copper and cobalt concentrations that were many times greater than the acute and chronic water quality criteria. The UAA removed the contact recreation uses based on natural low-flow conditions and removed the aquatic life beneficial use based on copper and cobalt concentrations.
In 2024, DEQ updated the 2002 UAA, reviewing available surface water quality data between 2003 and 2022. DEQ determined that total and dissolved copper and cobalt concentrations in Bucktail Creek decreased due to extensive remediation work within the drainage. Copper and cobalt concentrations in Bucktail Creek also decreased in downstream waters in South Fork Big Deer Creek. However, pollutant concentrations, specifically copper, are still above criteria due to human-caused conditions that have not been remedied to a point where the water body meets water quality standards or could support beneficial uses.
The final Review of Use Attainability Analysis for Bucktail Creek is available on DEQ’s website, and additional information can be found on DEQ’s Water Quality Standards web page.

State of Idaho finalizes land use transfers to support economic development and recreational opportunities in the Silver Valley
November 12, 2024
Contact: Andy Helkey, Kellogg Remediation Program Manager, Andy.Helkey@deq.idaho.gov
SHOSHONE COUNTY – The Idaho Department of Environmental Quality (DEQ) finalized three land transfers and a renewable lease agreement for property located within the Bunker Hill Superfund Site, helping advance local economic development and recreational opportunities throughout the area.
These actions, done in partnership with the Idaho Department of Parks and Recreation (IDPR), Idaho Department of Fish and Game (IDFG), and the city of Kellogg, open up almost 200 acres for public recreation and economic expansion in North Idaho.
“DEQ is excited to support new land use now that the cleanup work is complete for these properties,” said Dan McCracken, DEQ’s Coeur d’Alene Regional Office Administrator. “We believe that these transfers will help provide safe outdoor recreation access and promote local economic activity throughout the area.”
William Niska, manager of the Trail of the Coeur d’Alenes, said the move will open exciting opportunities for recreators along the 73-mile trail, giving users a place to rest and recuperate. “We appreciate DEQ’s willingness to support something new with the campground, which will reclaim this once-damaged ground for positive public use,” he said.
“The transfer of DEQ property to the city of Kellogg is viewed as a very forward-looking asset for the local community,” said Mike Fitzgerald, Public Works Director for the city of Kellogg. “The change provides perpetual public access to many properties fronting and located at the terminus of Government Gulch Road. Benefitting roadway users include over one dozen future commercially-industrially developable properties, Shoshone County’s Public Shooting Range, Shoshone County’s Equipment and Materials Storage Facility, city of Kellogg’s Materials Storage Facility, Central Shoshone County Water District’s future water storage and pumping facility, and multiple acreage properties currently under DEQ ownership.”
Superfund Cleanup Efforts
The Bunker Hill Superfund Site spans northern Idaho and into eastern Washington in an area known as the Silver Valley. Mining and milling operations started in the mid 1880s, which resulted in heavy metal contamination, including lead and other metals, throughout the area.
Exposure to these contaminants can pose serious human health risks, particularly to young children and pregnant women. As a result, the United States Environmental Protection Agency (EPA) added the Bunker Hill Superfund Site to the National Priorities List in 1983.
Cleanup efforts have reduced exposures over the last 30 years but require ongoing local oversight to ensure completed projects are properly maintained and future efforts continue. This is particularly important as land uses change in the Silver Valley and new residents move to the area.
Advancing Economic Opportunities
DEQ currently owns real estate parcels within the Bunker Hill Superfund Site, which were acquired from EPA. DEQ has authority to manage, lease, and dispose of this real property pursuant to Idaho Code 39-107A. Land transfer is conducted in accordance with DEQ Policy Statement PS-20-01 Bunker Hill Land Transfer Policy. Through these land transfers, DEQ and the State of Idaho are supporting the local economy and ensuring the Silver Valley is an area where people can live, work, and play.
The first transfer includes property located on the east side of Government Gulch Road. DEQ transferred the 9.8-acre parcel to a local excavating company, DG&S, providing an opportunity to construct a new facility and expand operations.
The second includes a property lease agreement for approximately 140 acres with IDPR for a bike-in campground along the Trail of the Coeur d’Alenes. The campground will have 26 bike-in/walk-in sites, a restroom/shower house, tent pads, and power hookups for recharging devices and e-bikes. Construction is planned for 2025.
The third includes a 40-acre parcel transfer to IDFG to expand an existing Wildlife Management Area north of I-90 and west of the Shoshone County Airport. The added property will help improve wildlife habitat and extend recreational opportunities.
The fourth transfer allows the city of Kellogg to designate the existing Government Gulch Road as a public right of way. The road was previously used as a private access point for the Bunker Hill Smelter Complex. Transfer of approximately four acres to the city opens up opportunities for local development and increases recreational opportunities for the public.
DEQ releases 2025 Idaho Pollutant Discharge Elimination System Program Permit Issuance Plan
November 1, 2024
Contact: Matt Stutzman, IPDES Individual Permit Supervisor, matthew.stutzman@deq.idaho.gov
BOISE – The Idaho Department of Environmental Quality (DEQ) today released the 2025 Idaho Pollutant Discharge Elimination System Program (IPDES) Permit Issuance Plan.
The plan provides the regulated community, United States Environmental Protection Agency (EPA), and other state, federal, tribal, and interested entities with information on permits being worked on for the next two years. It also prioritizes the facilities with pending permit applications and/or administratively continued permits under the IPDES Program.
DEQ assumed delegated authority for municipal, nonmunicipal, general, and stormwater permits on July 1, 2018, 2019, 2020, and 2021, respectively. With this change in authority, all permits for discharges into waters of the United States in Idaho not on tribal land are issued by DEQ, in accordance with the Memorandum of Agreement between DEQ and EPA.

DEQ to host Basin Advisory Group Chair meeting for FY2025 nonpoint source project evaluation
October 30, 2024
CONTACT: Bonnie Yoshizaki, Nonpoint Source Coordinator, bonnie.yoshizaki@deq.idaho.gov
BOISE – The Idaho Department of Environmental Quality (DEQ) is hosting a Basin Advisory Group Chair meeting to evaluate nonpoint source projects that are eligible for federal funding.
The meeting will be held in person and via Teams on November 13, 2024, from 9 a.m. to 1:30 p.m. Mountain Time. The in-person option will be held at DEQ’s State Office in Boise, Idaho. The public is encouraged to attend. See DEQ’s Events page for more information.
The funding is made available through Section § 319 of the Clean Water Act, which established a grant program under which states, territories, and tribes may receive funds to support a wide variety of nonpoint source pollution management activities. The Basin Advisory Group Chairs, which represent the six basin advisory groups statewide, are responsible for prioritizing nonpoint source project submissions for the upcoming fiscal year.
Nonpoint source pollution includes runoff from roadways, yards, construction sites, septic systems, and other sources, and is a significant concern for Idaho’s waterways. DEQ’s Nonpoint Source Management Program aims to prevent and eliminate pollution from nonpoint sources by implementing water quality improvement projects, which are designed to protect and restore beneficial uses (such as swimming and fishing) and prevent further water quality degradation.
DEQ seeks comment on draft 401 water quality certification for Pocatello Creek Road path project
Accepting comments from May 28, 2025, through June 18, 2025.
The Idaho Department of Environmental Quality (DEQ) is seeking comment on a draft water quality certification for the Pocatello Creek Road path project.
This project includes constructing a 10-foot wide, approximately 2,750-foot-long paved multi-use path to connect the Monte Vista neighborhood with the commercial district along Pocatello Creek Road. The path will be routed across Pocatello Creek using an existing structure to avoid the need to permit a new crossing. The existing structure is a corrugated metal pipe with a concrete headwall and wing walls. Disturbed areas from construction will be stabilized, reseeded with native vegetation, and restored to pre-construction conditions to minimize long-term erosion and sedimentation.
Based upon review of the federal permit application, readily available water quality related materials, and certification request in accordance with 40 CFR §§ 121.5 (b) and (c) and 121.7 (c) received on April 23, 2025, DEQ certifies that if the permittee complies with the terms and conditions imposed by the federal permit and 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 the Clean Water Act §§ 301, 302, 303, 306, and 307, Idaho’s “Water Quality Standards” (IDAPA 58.01.02), and other appropriate water quality requirements of state law.
Written comments will be accepted through June 18, 2025, at 5 p.m. Mountain Time. Submit comments electronically using the form below or by mail or email to:
