(a) Persons commencing Construction Projects after January 1, 2014, must obtain a Construction Site Runoff Control Permit prior to the commencement of Land-disturbing Activities.
(b) A written application, in a format provided by the General Manager, from the Applicant shall be submitted to the General Manager for each Construction Site Runoff Control Permit.
(c) An application for a Construction Site Runoff Control Permit shall include an Erosion and Sediment Control Plan for each Construction Project that conforms to the format and criteria provided by the General Manager.
(d) The General Manager may grant or deny the Construction Site Runoff Control Permit, or require further information or analysis pertinent to compliance with this Article.
(e) The Permittee shall maintain a copy of the Construction Site Runoff Control Permit and approved plans and reports required under the permit on the work site and available for public inspection during all working hours.
(a) The Erosion and Sediment Control Plan shall include a vicinity map showing the location of the site in relationship to the surrounding area's water courses, water bodies, and other significant geographic features; a site survey; suitable contours for the existing and proposed topography, area drainage, proposed construction and sequencing, proposed drainage channels; proposed erosion and sediment controls; dewatering controls where applicable; soil stabilization measures where applicable; maintenance controls; sampling, monitoring, and reporting schedules; and any other information deemed necessary by the General Manager.
(b) Any Person performing Land-disturbing Activities at sites greater than or equal to one acre within a separate sewer system area may submit to the General Manager the Storm Water Pollution Prevention Plan (SWPPP) used to comply with the State of California's General Permit for Discharges of Storm Water Associated with Construction Activity in lieu of an Erosion and Sediment Control Plan.
(a) Daily Maintenance. The Permittee shall daily inspect, maintain, and repair all graded surfaces and erosion and sediment controls, drainage structures, and other protective devices, plantings, and ground cover installed while construction is active.
(b) Reporting. Every person who operates any erosion and sediment control or controls must provide inspection and maintenance information as set forth in the Construction Site Runoff Control Permit, and certify under penalty of perjury that such information is accurate and true.
(c) Inspections. Permittees shall permit the General Manager to perform inspections as may be deemed necessary in the General Manager's sole discretion to carry out the intent of this Article.
(d) Milestone Notification. The Permittee shall notify the General Manager at least two working days before the following milestones occur:
(1) Start of construction.
(2) Erosion and sediment control measures are completely installed and stabilized.
(3) Final grading has been completed.
(4) Project completion.
(e) Authority to Sample and Establish Sampling Devices. Permittees shall provide devices or locations necessary to conduct sampling or metering operations, if requested by the General Manager.
(f) Requirement to Test or Monitor. Permittees shall undertake such monitoring activities or analysis and furnish such reports as the General Manager may specify, if requested by the General Manager.
(g) Notification of Spills. All Persons responsible for implementing BMPs shall provide immediate notification to the General Manager of any suspected, confirmed or unconfirmed release of Pollutants that creates a risk of non-stormwater discharge into any of the City's sewer systems. Such persons shall take all necessary steps to ensure the detection and containment and cleanup of such release.
(h) Public Right-of-Ways. The Permittee shall be responsible for the prompt removal of, and the correction of damage resulting from any soil, miscellaneous debris or other materials washed, spilled, tracked dumped or otherwise deposited on public streets, highways, sidewalks or other public thoroughfare, incident to the construction activity, or during transit to and from the construction site.
Persons violating any provision of the Construction Site Runoff Control Permit or Sections 146-146.11 of this Article or applicable laws or regulations are subject to enforcement by the General Manager pursuant to Section 132 of Article 4.1 of this Code. Persons violating Sections 146-146.11 of Article 4.2
or applicable laws or regulations are subject to penalties and abatement in accordance with Sections 133 and 134 of Article 4.1 of this Code, and any other remedies allowed by law.
For construction projects in areas of the City under the jurisdiction of the Port Commission, the Port’s Executive Director or his or her designee shall have enforcement authority identical to the enforcement authority referenced in the two preceding sentences.
If any section, subsection, subdivision, paragraph, sentence, clause, or phrase is for any reason held to be unconstitutional, invalid or ineffective by any court of competent jurisdiction, such decision shall not affect the validity or effectiveness of the remaining portions of this Article. The Board of Supervisors declares that it would have passed each section, subsection, subdivision, paragraph, sentence, clause, or phrase irrespective of the fact that any one or more sections, subsections, subdivisions, paragraphs, sentences, clauses, or phrases could be declared unconstitutional, invalid or ineffective.
(a) The intent of Sections 147-147.6 of this Code is to reduce the volume of stormwater entering the City's Combined and Separate Sewer Systems and to protect and enhance the water quality of receiving waters, pursuant to, and consistent with Federal and State laws, lawful standards and orders applicable to stormwater and urban runoff control, and the City's authority to manage and operate its drainage systems.
(b) Urban runoff is a significant cause of pollution throughout California. Pollutants of concern found in urban runoff include sediments, non-sediment solids, nutrients, pathogens, bacteria, oxygen-demanding substances, petroleum hydrocarbons, heavy metals, floatables, polycyclic aromatic hydrocarbons (PAHs), trash, and pesticides and herbicides.
(c) During urban development, two important changes occur. First, where no urban development has previously occurred, natural vegetated pervious ground cover is converted to impervious surfaces such as paved highways, streets, rooftops, and parking lots. Natural vegetated soil can both absorb rainwater and remove pollutants, providing a very effective purification process. Because pavement and concrete can neither absorb water nor remove pollutants, the natural retention and purification characteristics of the land are lost, increasing the volume of stormwater entering the collection system and the concentration of pollutants within that water. Second, urban development creates new pollutant sources, including vehicle emissions, vehicle maintenance wastes, pesticides, household hazardous wastes, pet wastes, trash, and other contaminants that can be washed into the City's Separate or Combined Sewer Systems.
(d) A high percentage of impervious area correlates to a higher rate of stormwater runoff, which generates greater pollutant loadings to the City's Separate and Combined Sewer Systems, resulting in turbid water, nutrient enrichment, bacterial contamination, toxic compounds, temperature increases, and increases of trash or debris.
(e) When stormwater impacts are considered during the planning stages of a project, new development and redevelopment projects can more efficiently incorporate Post-Construction Stormwater Controls that will enhance the function and capacity of the City's Separate and Combined Sewer Systems by providing pretreatment of stormwater and protecting water quality.
(1) reducing stormwater runoff rates and volume whenever possible through Post-Construction Stormwater Controls, and ensuring that these stormwater controls are safe and properly maintained;
(2) minimizing increases in pollution caused by stormwater runoff from development that would otherwise degrade local water quality; and
(3) controlling the discharge of contaminants to the City's sewer and drainage systems through spills, dumping, or disposal.
