Stockton Municipal Code Art. II Permit Regulations and Requirements

Priority projects, priority land use (PLU) projects, or projects that are both a priority project and a PLU project shall incorporate stormwater pollution control measures (site design controls, source controls, volume reduction measures, and/or treatment controls), as applicable to minimize stormwater quality impacts to the MEP. The Director has the authority to require a SWQCP, maintenance plan, and/or other materials upon determining the project is subject to the SWQCCP.

The SWQCP and maintenance plan must be approved by the City's Municipal Utilities Department (MUD). A maintenance agreement with the City must be executed by the owner/operator and inspection conducted by the City of the control measures that have been implemented to ensure that they meet the design standards and conform with the approved plans.

The permit holder shall be responsible for the development and implementation of an effective SWQCP, maintenance plan, and/or other materials as required by the SWQCCP. The permit holder shall also allow the City to inspect the development site and review the implementation of the control measures as needed. Such plans, materials, and incorporated controls/measures may be evaluated by the authorized enforcement officer and shall be required to be in compliance with the following provisions:

A. Stormwater Quality Control Plan.

1. A SWQCP shall be developed and implemented by the permit holder for each priority project and/or PLU project to minimize the potential adverse impacts to water quality that may occur after the project is complete.

2. Consistent with the process outlined within the SWQCCP, each SWQCP shall evaluate and include site design controls, source controls, volume reduction measures, and treatment controls. In addition, all priority projects and/or PLU projects must also apply trash control measures. The steps for developing the SWQCP are outlined within the SWQCCP and generally include the following:

a. Determine project type;

b. Collect site information;

c. Apply site design controls;

d. Apply source controls;

e. Apply volume reduction measures;

f. Apply treatment controls;

g. Select additional treatment controls as needed to meet treatment requirement;

h. Submit project stormwater quality control plan.

B. Maintenance Plan and Agreement.

1. A maintenance plan shall be developed and implemented by the permit holder for each priority project and/or PLU Project to ensure that the controls incorporated into the project are operated and maintained as originally intended and to ensure the effectiveness of the controls. The plan must include guidelines for how and when inspection and maintenance should occur for each control. In addition, the maintenance plan must acknowledge that the City may request information about the operation and maintenance of the control measures implemented on an ongoing basis and/or may come on-site to conduct independent inspections of the control measures, as needed.

2. Consistent with the SWQCPP, the maintenance plan should, as applicable, include the following:

a. Site map;

b. Baseline description;

c. Spill plan;

d. Facility changes;

e. Training;

f. Basic inspection and maintenance activities;

g. Revisions to pollution migration measures;

h. Monitoring and reporting program.

3. Consistent with the SWQCPP, the Director requires the submittal, approval, and execution of a maintenance agreement with the owner/operator of stormwater controls prior to the final acceptance of a priority project and/or PLU project incorporating any of the structural source controls that require maintenance, volume reduction measures, and treatment controls.

The maintenance plan and agreement shall be submitted in the format requested by the Director.

As the new development and significant redevelopment projects are developed and constructed, they shall be in conformance with the applicable drainage standards as specified in the City's standard specifications and plans, the City's Grading and Erosion Control Ordinance, and any applicable provisions pursuant to Chapter 15.48.

Projects may also be subject to, and thus should be aware of, the requirements and provisions of the California General Industrial Stormwater Permit, the California General Construction Activity Stormwater Permit, and/or the Federal Stormwater Effluent Limitation Guidelines.
