The Enforcement Program's primary responsibilities are:

  • Evaluating and prioritizing violations of water quality protection laws, regulations, and permits.
  • Effectively initiating and following through on enforcement actions/strategies intended to reestablish compliance, to address environmental damage, and to deter future violations.
  • To coordinate with other Regional Water Boards and the State Water Board in pursuing multi-region or state-wide enforcement actions; and to improve enforcement consistency and effectiveness.

These actions are conducted under federal and state law, and the State Water Board's Water Quality Enforcement Policy, with one allocated position and with resources from other programs.

The Enforcement Fact Sheet provides more information on the Goals, Types of Enforcement Actions, Accomplishments, Performance Targets for the current year and following year.

Supplemental Environmental Projects – Information, Current SEP List, Form to Submit New SEP Proposal

Proposed settlements of Administrative Civil Liability (ACL) Complaints may include a supplemental environmental project (SEP) to offset a portion of the total liability. When a proposed settlement includes a SEP, the SEP is included in an ACL Order that is presented to the Water Board at a public hearing. The Water Board can either accept or reject the ACL Order as proposed with the SEP.

Below are links that provide: (1) general information about SEPs, (2) specific information about SEPs that have been accepted by the Lahontan Water Board and are in progress or have been completed, and (3) instructions about how to submit a project proposal for inclusion on the Lahontan Water Board's SEP List.
