Non-Priority Project Water Quality Plan (NPP)
The Orange County Stormwater Program has developed this Non-Priority Project Water Quality Plan (NPP) for new development / significant redevelopment projects that do not meet the criteria
for Priority Projects as defined within the County’s Model Water Quality Management Plan (see Model WQMP Sections 1.3 and 1.4) but that qualify as Non-Priority Projects as defined in
the Drainage Area Management Plan (DAMP). These projects are required under the Santa Ana Regional Board MS4 Permit (North Orange County Permit) to “document, via a WQMP or similar
mechanism, site design, source control and any other BMPs which may or may not include treatment control BMPs”. There is no similar requirement under the San Diego Regional Board MS4
Permit (South Orange County). This plan covers both private and public agency projects that qualify as Non-Priority Projects.
Qualifying Non-Priority Projects are projects that do not fall under one of the Priority Project Categories defined within the Model WQMP but meet one of the following conditions:
Require discretionary action that will include a precise plan of development, except for those projects exempted by the Water Quality Ordinance (as applicable); or
Require issuance of a non-residential plumbing permit for hazardous pipelines as defined in the County or local Water Quality / Stormwater Ordinance. Non-residential plumbing projects
that do not pose a potential threat to public safety do not require a WQMP for approval.
A “discretionary action” under CEQA is defined as “an activity which requires the public agency to exercise judgment in deciding whether to approve or disapprove the particular activity,
as distinguished from situations where the public agency merely has to determine whether there has been conformity with applicable ordinances or other laws.” (California Public Resources
Code § 21080(a); CEQA Guidelines § 15357). Examples of discretionary actions include: feature plans, area plans, use permits, site development permits and special use permits. “Ministerial
actions” under CEQA are those where little or no judgment or deliberation by a Permittee is required or possible. Generally, the only example of a ministerial approval action that would
qualify as a Non-Priority Project would be a project that requires the issuance of a Non-Residential Plumbing Permit.
All other projects and activities that only require a ministerial grading or building permit for which the Permittee has no discretion to approve do not fall under the requirements of
this new development program, with the exception of projects that require a Non-Residential Plumbing Permit.
This plan is provided for summarizing basic project information and stormwater Best Management Practices that are planned for controlling discharges of pollutants from proposed Non-Priority
Projects and identify applicable source conrol BMPs, site design features, and determine BMP maintenance requirements. Non-Priority Project proponents are required to complete the plan
for local jurisdiction review and approval. Applicable sections of the Technical Guidance Document are referenced for assistance with completing each NPP section. All Non-Priority Project
Water Quality Plans must be in compliance with the Local Implementation Plan developed by each local agency. The local jurisdiction may request additional information necessary for
local Non-Priority Project review and approval.
Local jurisdictions may modify existing templates for local program implementation to incorporate the information contained in this Plan provided all information necessary to meet requirements
contained in the MS4 Permit and the DAMP for Non-Priority Projects are contained within the local plan.
