A. Water Pollution Prevention. The Contractor shall plan for and implement temporary construction BMPs to mitigate the water quality impacts of land disturbance and non - storm water discharges related to construction activities in accordance the Agency’s current Municipal Stormwater Permit and Carlsbad Municipal Code Chapter 15.12. BMPs are the schedules of activities, prohibitions of practices, maintenance procedures and other management practices employed during construction activities to prevent or reduce pollution of bodies of water protected by the federal Clean Water Act (33 U.S.C. § 1251 et seq. ) and the state Porter -Cologne Water Quality Control Act (Water Code , § 13000 et seq.), which include oceans, lagoons, lakes, streams and other sensitive water bodies and water courses. Construction BMPs also include physical devices and structural construction control measures designed to prevent soil erosion from occurring on the Work Site, or that are designed to prevent sediment from leaving the Work Site, both of which are referred to hereafter as “Water Pollution .” BMPs are also intended to protect
01 41 26 PERMIT REQUIREMENTS Date Printed: February 26, 2024 Document Version: 1.0 Current Update: May 2023
the health, safety and welfare of the public and to prevent damage to adjoining public and private property resulting from construction activities.
B. Pollution prevention practices and the minimum BMPs are required during all 12 months of the year. BMPs and other erosion control practices must be implemented as the most important “first line of defense .” The Agency has adopted the CASQA ‘Stormwater Best Management Practices Handbook: Construction ,’ latest edition, as its preferred source for adopting construction BMPs. All BMPs must correspond to the BMP Fact Sheets included in the CASQA Construction Handbook. With the approval of the Engineer, or designee, the Agency may accept comparable BMPs fro m reputable alternative sources.
As used in this section, “Engineer” shall have the same meaning as “Construction Manager.”
C. The Contractor shall utilize the Agency’s Tier 1 or Tier 2 SWPPP templates and include all applicable elements provided in the template. The SWPPP templates are available on the Agency’s website at [PROJECT ENGINEER insert website address here]. Tier 1 and Tier 2 SWPPP templates include standard storm water prevention construction notes, a Project information block, a Storm Water Compliance Statement, Agency approval block and a BMP Checklist Table. The BMP Checklist Table is intended to help the Contractor select appropriate BMPs best suited to the Project and the Work. Additionally, the SWPPP shall include a Site plan showing the proposed Project Site and depicting the areas of proposed construction and proposed locations of construction BMPs. The Tier 1 and Tier 2 SWPPP plans shall be submitted as additional sheets to the construction plan set.
D. The Engineer may require Contractor to adopt additional BMPs if the Engineer determines the selected BMP(s) are ineffective or incapable of preventing Water Pollution from escaping the Work site. Tier 1 and Tier 2 SWPPPs must be combined with proper and timely installation of the BMPs, thorough and frequent inspections, maintenance, and documentation. The Contractor shall ensure that the selected BMPs are appropriately incorporated into the Site design and, if required by the Engineer, must employ a qualified professional to ensure proper installation and maintenance of the BMPs.
E. The Engineer may suspend the Work, consistent with Supplemental General Provisions Section 6 -6, at the Contractor’s cost, that create Water Pollution or otherwise violate water quality standards required by the federal Clean Water Act (33 U.S.C. § 1251 et seq.) and the state Porter-Cologne Water Quality Control Act (Water Code , § 13000 et seq.) if the Engineer determines that the Contractor has failed to satisfy all requirements of this section. If the Contractor violates any provisions of this subsection, or if Water Pollution occurs in the Work Site for any reason, the Contractor shall immediately notify the Engineer.
F. The Contractor shall immediately notify the Agency if there is a non-stormwater discharge to the storm drain conveyance system resulting from the Work or Project-related activities. In addition, the Contractor shall, within 24 hours, submit a written report to the Engineer describing the incident and corrective actions taken. If for any reason the Engineer detects Water Pollution, before notification by the Contra ctor, this written report shall also include an explanation of why the Contractor had not timely notified the Engineer.
