Public Notice: Proposed Decision to Revise Permit Conditions for Evoqua Water Technologies LLC, Parker, Arizona

Publish Date: 10/04/2019


The United States Environmental Protection Agency (EPA) [Region 9, Land, Chemicals, and Redevelopment Division, 75 Hawthorne Street, San Francisco, CA 94105] is requesting public comment on proposed revisions to permit conditions in the hazardous waste management permit for the Evoqua Water Technologies LLC facility located at the Colorado River Indian Tribes’ Reservation, 2523 Mutahar Street near Parker, Arizona.

The proposed revisions for which EPA is requesting public comment were the subject of an EPA Environmental Appeals Board (EAB) decision dated June 13, 2019. That decision was the result of an appeal of EPA’s September 25, 2018 hazardous waste permit, in which the EAB denied review on all but three issues raised in the appeal. Those three issues were “remanded” to EPA and are the subjects of EPA’s proposed decision. They involve: (1) the process by which the Permittees are required to report certain instances of non-compliance; (2) the appropriate regulation of Tank T-11; and (3) the technical feasibility of complying with certain Automatic Waste Feed Cutoff (AWFCO) requirements. During the public comment period, comments may only be made on these three remanded items. The remainder of the permit is not open for review.

Public Meeting Invitation

EPA invites you to attend a public meeting and public hearing to discuss the proposed permit decision and to collect verbal and written comments. The meeting will be held November 7, 2019, in the Mohave Conference Room at the Bluewater Resort and Casino, located at 11300 Resort Drive, Parker, Arizona, 85344 (phone number: 928-669-7000).
