Nonhazardous Solid Waste Impoundment Guidance


First public meeting with stakeholders scheduled for May 22, 2019.


DEQ invites the public to participate in the development of guidance pertaining to the regulation of nonhazardous solid waste impoundments under the Solid Waste Management Rules (IDAPA 58.01.06). This type of waste is sometimes referred to as “pumpable” waste. The guidance will apply to facilities commercially receiving solid waste from off-site where: (1) the facility is not within the site certified area of an approved landfill, (2) the waste does not pass the paint filter test prior to placement in the impoundment unit, and (3) operations are not otherwise regulated under a discharge or land application permit.

Facilities engaged in food processing or other manufacturing or industrial activities with onsite treatment of liquid waste are not affected by this guidance initiative. Those facilities generally are not regulated under IDAPA 58.01.06 because oversight is through discharge permits or land application permits.

Stakeholders may include: Owners and operators of existing or proposed impoundment facilities commercially accepting liquid or “pumpable” waste, pumpable waste haulers and generators, local governments addressing issues related to these facilities, and the affected public. Owners and operators of approved landfills with impoundment facilities inside and outside their certified areas commercially accepting liquid waste may want to participate since the same operational measures will be expected whether facility oversight is under a landfill operating plan or a separate authorization.

For more information on this guidance initiative, including its background, scope, and goals, please refer to the Discussion Paper: Nonhazardous Solid Waste Impoundments (NSWIs) in Idaho. Prior to the first stakeholder meeting an outline of the proposed guidance will be posted on this webpage. Please check back often as the contents of this page will change.
