Storm Water Pollution Prevention Plan

CATEGORY OF SERVICE, LOCATION:

Irrigated Lands Regulatory Program, Watsonville, California

TYPE OF CLIENT:

Property Owner - Farmer

BACKGROUND:

 Irrigated lands regulatory program, watsonville, california

Irrigated lands regulatory program, watsonville, california

  • The owner (“discharger”) of commercially irrigated land received a directive from the California Central Coast Regional Water Quality Control Board (CCRWCB) requiring the owner to obtain regulatory coverage for his irrigated land within 15 calendar days of receiving the directive. Failure to comply would result in financial penalties up to $1,000 per day.
  • Regulatory coverage required the submission of a Notice of Intent (NOI) and compliance with requirements of the Conditional Waiver of Waste Discharge Requirements for Discharges from Irrigated Lands (Order No. R3-2017-0002) also known as the Agricultural Order (Order). 

 

CLIENT GOALS FOR PROJECT:

Client requested Trinity to assist with the timely submission of the Notice of Intent and consultation for compliance with the requirements of the Agricultural Order.

PROJECT APPROACH:

  • Trinity assessed the client’s farm operation and Tier Classification by consulting with the owner, in conjunction with the leased grower, to answer questions pertaining to the Notice of Intent (NOI); the NOI served as a Report of Waste Discharge for the commercially irrigated land.
  • At the time of NOI submittal, the discharger must elect cooperative or individual options for both Surface Receiving Water Monitoring and Reporting and Groundwater Monitoring and Reporting. Trinity assessed the cost/benefit for each option based on the characteristics of the farming operation, and determined the discharger should elect for Individual (Qualified Laboratories) Groundwater Monitoring and Reporting and a Cooperative (Coalition Group) Surface Receiving Water Monitoring and Reporting.

RESULTS, RESOLUTION, NEXT STEPS:

  • Trinity submitted the NOI to the CCRWCB  prior to the 15‑calendar day deadline.
  • The Central Coast Regional Water Board determined the discharger’s operation was Tier 1. Trinity works with the discharger to meet the ongoing conditions of the 3-Year Compliance Calendar for the Order as it pertains to Tier 1, which includes, but is not limited to, drafting and updating of a Farm Water Quality Plan and biannual monitoring of groundwater parameters which are submitted to the CCRWCB  within 60 days of sampling.

Storm Water Pollution Prevention Plan (SWPPP) Implementation, Scotts Valley, California

TYPE OF CLIENT:

Developer

BACKGROUND:

The client purchased the site and plans to redevelop the property for commercial use by constructing a restaurant/sports bar. Per the California State Water Board’s Construction General Permit (CGP), a SWPPP was developed by a Qualified SWPPP Developer (QSD) from SWPPP Solutions, Inc. to address storm water and possible pollutants during active and inactive construction phases.

CLIENT GOALS FOR PROJECT:

Meet the California State Water Resources Control Board’s CGP requirements to protect the quality of the receiving waters from the discharge from the site before, during, and after construction phases in accordance with the SWPPP developed for the site. The client contracted Trinity to perform Qualified Stormwater Practitioner (QSP) activities throughout the active and inactive construction phases.

PROJECT APPROACH:

  • Protect the environment from the discharge by reducing the sediment and other pollutants generated during the rain event by complying with the Construction General Permit.
  • Prepare Rain Event Action Plans (REAPs) for each phase of construction and for each rain event with more than 0.5 inch of forecasted rain by checking NOAA rain forecasts bi-weekly.
  • The QSP is responsible for the inspection, maintenance, repair, and sampling activities unless the QSP trains the client’s employees. The client and the general contractor were trained by the QSP to handle on-site SWPPP implementation tasks saving significantly on inspection and sampling costs.
  • The client is notified within 48-hours of a rain event by the QSP to inspect the site and ensure stormwater Best Management Practices (BMPs) are in-place and working correctly.

RESULTS, RESOLUTION, NEXT STEPS:

Continue to assist the client with SWPPP implementation through the rainy season and into the active construction phase.

Industrial Storm Water Pollution Prevention Plan (SWPPP)

TYPE OF CLIENT:

Industrial - Shock Absorber Manufacturing
Scotts Valley, California

BACKGROUND:

A manufacturing company requested assistance with the State Water Resources Control Board’s (SWRCB’s) National Pollutant Discharge Elimination System (NPEDS) General Permit for Storm Water Discharges associated with industrial activities. The Santa Cruz County Environmental Health Services Agency (SCCEHSA) requested that the client implement a plan to prevent potential contaminants from an outdoor above ground storage tank (AST) and a hydraulic pump from entering nearby storm drains during dry and wet (storm) events.
Because the AST and hydraulic pump were outside and not covered the client could not apply for the no exposure certification (NEC) coverage under the general permit.

CLIENT GOALS FOR PROJECT:

To address the SCCEHSA’s request by implementing a plan to protect two storm drains at the Site from possible leaks/spills related to an outdoor AST and hydraulic pump.

PROJECT APPROACH:

  • Trinity designed a pollution prevention plan to address possible spills/leaks related to the outdoor AST and hydraulic pump during dry and wet weather.
  • The SWPPP included contact information in case of a spill or release, the responsible party, a storm water pollution prevention team, potential pollutant sources, and how to address spills and leaks during an emergency.
  • Trinity developed best management practices which included good housekeeping, drain inlet protection during dry and wet events with a high strength impermeable drain seal, inspection protocols during rain and non-rain events to ensure the drain is protected, and a 95-gallon spill kit for the potential contaminants of concern.
  • The SWPPP also included procedures for daily and weekly inspections during rain and non-rain events, and record keeping to comply with the industrial General Permit.
  • A Qualified Storm Water Developer (QSD) and Qualified Industrial Storm Water Practitioner (QISP) from Trinity initially trained the SWPPP team at the manufacturing facility on the AST and hydraulic pump SWPPP.
  • Trinity designed the SWPPP so that the SWPPP team managers can conduct the recurrent annual training in-house.

RESULTS, RESOLUTION, NEXT STEPS:

  • The SCCEHSA approved of the SWPPP with no comments and agreed the SWPPP adequately protected the contaminants from entering the storm drains during rain and non-rain events.
  • The client is currently implementing the SWPPP.
