1.23 BMP C160 - Erosion and Sediment Control Lead
The project proponent must designate at least one person as the responsible representative in charge of erosion and sediment control (ESC) and water quality protection. The designated person shall be the erosion and sediment control (ESC) lead, who is responsible for ensuring compliance with all local, state, and federal erosion and sediment control and water quality requirements.
An erosion and sediment control contact is required for all project sites.
A certified erosion and sediment control lead (CESCL) or certified professional in erosion and sediment control (CPESC) is required on projects that include, but are not limited to:
Construction activity that disturbs one acre of land or more.
Projects disturbing less than one acre must have an Erosion Sediment Control Lead (ESC) conduct inspections. The ESC Lead does not have to have CESCL or CPESC certification.
The CESCL, CPESC, or ESC Lead shall be identified in the SWPPP and shall be onsite or on-call at all times.
The CESCL, CPESC, or ESC Lead must be knowledgeable in the principles and practices of erosion and sediment control and have the skills to assess:
Site conditions and construction activities that could impact the quality of stormwater.
Effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges.
Have a current certified erosion and sediment control lead (CESCL) certificate proving attendance in an erosion and sediment control training course that meets the minimum ESC training and certification requirements established by Ecology.
For additional information concerning the Certified Professional in Erosion and Sediment Control program please go to https://envirocertintl.org/cpesc/.
The ESC lead shall have authority to act on behalf of the contractor or developer and shall be available, on call, 24 hours per day throughout the period of construction.
The Construction SWPPP shall include the name, telephone number, email, and address of the designated ESC lead.
An ESC lead may provide inspection and compliance services for multiple construction projects in the same geographic region.
Duties and responsibilities of the ESC lead shall include, but are not limited to, the following:
Inspecting all areas disturbed by construction activities, all BMPs and all locations where runoff leaves the site at least once every calendar week and within 24 hours of any discharge from the site. The ESC lead may reduce the inspection frequency for temporary stabilized, inactive sites to monthly.
Examining stormwater visually for the presence of suspended sediment, turbidity, discoloration, and oil sheen.
Evaluating the effectiveness of BMPs.
Maintaining a permit file onsite at all times which includes the SWPPP and any associated permits and plans.
Directing BMP installation, inspection, maintenance, modification, and removal.
Updating all project drawings and the Construction SWPPP with changes made.
Keeping daily logs and inspection reports. Inspection reports should include:
Weather information, general conditions during inspection, and approximate amount of precipitation since the last inspection.
A summary or list of all BMPs implemented, including observations of all erosion/sediment control structures or practices. The following shall be noted:
Locations of BMPs that need maintenance,
Locations of BMPs that failed to operate as designed or intended, and
Locations where additional or different BMPs are required.
Visual monitoring results, including a description of discharged stormwater. The presence of suspended sediment, turbid water, discoloration, and oil sheen shall be noted, as applicable.
Any water quality monitoring performed during inspection.
General comments and notes, including a brief description of any BMP repairs, maintenance, or installations made as a result of the inspection.
Facilitate, participate in, and take corrective actions resulting from inspections performed by outside agencies or the owner.
