DEQ seeks comment on proposed settlement action with city of Blackfoot

Accepting comments from September 17, 2025, through October 18, 2025.

The Idaho Department of Environmental Quality (DEQ) is seeking public comment on a proposed settlement action and consent judgment with the city of Blackfoot for alleged violations of the Clean Water Act and Idaho Pollutant Discharge Elimination System (IPDES) permitting requirements.

Under IPDES Permit ID0020044, the city is authorized to discharge treated wastewater from its publicly owned treatment works in Blackfoot, Idaho, to the Snake River. DEQ alleges the city exceeded effluent limits, failed to submit required discharge monitoring reports on time, allowed sanitary sewer overflows, and failed to implement required pretreatment controls for industrial users.

The proposed settlement action requires the city to address deficiencies in its collection system and pretreatment program, complete facility upgrades, and submit regular progress reports. The city must also pay a civil penalty of $56,805, with an additional $227,220 in stipulated penalties that may be assessed if the city fails to meet specific compliance milestones outlined in the settlement action.

In compliance with Idaho Code §39-108(9) and the “Idaho Pollutant Discharge Elimination System Rules” (IDAPA 58.01.25.500.04), DEQ is publishing the proposed settlement action for public comment. The materials are available for review at DEQ’s State Office (1410 N. Hilton St., Boise, Idaho) and on DEQ’s website, and written comments will be accepted through October 18, 2025, at 5:00 p.m. MST. The proposed settlement action may be amended or adjusted in the future, in which case DEQ may provide an additional public comment opportunity.

DEQ seeks participation in private well sampling event in Star, Idaho

September 3, 2025

Contact: Skye Bensel, Water Quality Scientist, Skye.Bensel@deq.idaho.gov

STAR – The Idaho Department of Environmental Quality (DEQ) is reaching out to private well owners in the Northeast Star Nitrate Priority Area, near Star, Idaho, to participate in a sampling event.  

Sampling will test for nitrates, arsenic, uranium, bacteria, and common ions at private wells, and will take place in September and October of this year. Participation is free and well owners will receive a copy of the results. 

DEQ maintains a list of degraded groundwater areas throughout the state, which are referred to as nitrate priority areas. The Northeast Star sampling event will revisit sites sampled by DEQ and other agencies prior to 2021. The sampling will also include new locations to update the nitrate concentration data in this region. Outcomes will help DEQ better understand nitrate levels in the aquifer and help local decision makers implement best management practices.  

Once results are analyzed, information will be provided to the private well owners, which can be used to help protect the quality of their well water and the health of those relying on it.  

Groundwater provides over 95% of Idaho’s drinking water and nitrate is the most common and widespread contaminant in groundwater. Nitrate exposure can have serious health effects, but certain groups are particularly vulnerable, including people with pre-existing health conditions, pregnant women, and young children under the age of six months. Infants who drink water containing nitrate above the maximum contaminant limit can become seriously ill and, if untreated, may die. Symptoms include shortness of breath and blue-baby syndrome, also known as Methemoglobinemia. This condition can occur rapidly, over the course of just a few days. Do not attempt to remove nitrate from drinking water by boiling it. This will concentrate nitrate levels. 

If you are interested in participating, contact Skye Bensel at (208) 805-2070 or Skye.Bensel@deq.idaho.gov by September 16, 2025.

Protect yourself and your pets from harmful algal blooms this summer 

June 26, 2025

Track water sampling locations and health advisories: 

Report a potential harmful algal bloom: 

BOISE – Summer is peak season for harmful algal blooms (also known as blue-green algae, cyanobacteria harmful algal blooms, or HABs) and Idahoans are reminded to stay safe and protect their pets when recreating in and around water. 

Cyanobacteria are naturally occurring aquatic organisms. However, under certain conditions, the bacteria can produce toxins that affect human health and the environment. Humans and animals can be exposed to cyanotoxins by swimming in or swallowing water impacted by a bloom or consuming fish caught in affected waterbodies. Swallowing water impacted by a bloom can cause stomach pain, nausea, and vomiting. Direct skin contact may also cause skin and eye irritation. 

Pets, livestock, and wildlife are especially prone to cyanobacteria exposure because they are more likely to swim in or drink affected water. If your pet or livestock is exposed to water containing a suspected or confirmed bloom, wash them immediately with freshwater and soap, and do not let them lick their fur. Seek veterinary care immediately if your pets or livestock seem sick after going in or near water. 

Harmful algal blooms can vary in appearance but can often look like pea soup, grass clippings, spilled paint, mats, green or blue-green foam, or dense surface scum. Some blooms may produce a foul odor. 

The following safety tips can help you and your pets stay safe this summer: 

  • Check the Idaho Department of Health and Welfare’s Recreational Water Health Advisories Map for active health advisories before visiting Idaho’s water bodies. Following health advisories will reduce your chance of exposure and potential illness. 
  • Check the Idaho Department of Environmental Quality’s Cyanobacteria Harmful Algal Bloom web page for current water quality sampling data. 
  • When in doubt, stay out and keep your pets and livestock out of the water.

BOISE – The Idaho Department of Environmental Quality (DEQ) today announced the award of a $16,500,000 low-interest drinking water construction loan to the city of McCall in Valley County, Idaho.

The funding will be used to address storage capacity needs through the construction of a new water storage tank. Additionally, the water treatment facility will be expanded by adding two new filters, upgrading its electrical and control systems, and expanding the clearwell to increase disinfection capacity. Lastly, storage facilities will be added for operational equipment and materials.

DEQ is authorized by state law to make loans to assist in the construction of public drinking water systems. This loan from DEQ’s State Revolving Loan Fund, which is capitalized annually by grants from the U.S. Environmental Protection Agency, carries a simple 2.75% interest rate and is payable over 20 years. The favorable loan terms represent a $4,809,463 savings to the community when compared to average costs for municipal general obligation debt issuances.

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.
