CTACG & CTASWP Membership


Transportation facilities that perform maintenance, including fueling and washing, may need storm water permit coverage. Since 1999, NES has served as the Technical Group Leader for the California Trucking Association Storm Water Compliance Group (CTACG), one of the largest storm water compliance groups in the State of California.

Storm water regulations allow facilities with similar industrial activities and classifications to join compliance group programs, such as the CTACG. A storm water compliance group reduces individual member costs and enables a broader understanding of developing and implementing best management practices (BMPs) common to the trucking industry. CTA member facilities with the primary Standard Industrial Classification (SIC) codes of 4212, 4213, 4214, and 4231 are able to join the CTACG.

Additionally, NES administers the California Trucking Association Storm Water Program (CTASWP) for those facilities not eligible to join the compliance group based on SIC code. NES provides CTACG & CTASWP member facilities with the following storm water benefits:

NES Storm Water Compliance Program

Members are provided with the documents necessary for implementing a cost-effective Storm Water Pollution Prevention Program:

  • Storm Water Pollution Prevention Plan (SWPPP) template
  • Monitoring program forms and guidance documents
  • Simplified visual observation forms

NES reviews member-submitted storm water documents to verify accuracy and completeness. Documents include:

  • SWPPP and site map
  • Monthly visual observation forms
  • Sampling event visual observation forms
  • Annual Report

NES also assists member facilities in completing the electronic Annual Report Questionnaire on the SMARTS Database.

Facilities are required to collect storm water samples to identify potential pollutants discharging from industrial activity areas. Facilities participating in the CTACG are required to collect 2 samples per reporting year, representing a 50% reduction compared to facilities not in a compliance group (CTASWP facilities will still be required to collect 4 samples per reporting year).

As part of the annual CTACG & CTASWP membership fee, NES provides member facilities with:

  • Storm water sampling kits
  • Guidance documents
  • Pre-paid shipping labels
  • Laboratory analysis
  • Detailed reports of analytical results

CTACG & CTASWP members receive an annual site visit by NES to assist with adherence to the Industrial General Permit. These site visits are conducted by the Compliance Group Leaders and are geared towards preparing facilities for formal regulatory inspections by the Water Board. Each site visit includes:

  • Thorough review of storm water documents
  • Site walk to observe industrial activities performed on-site
  • Recommendations for applicable BMPs

The NES storm water team is Qualified Industrial Storm Water Practitioner (QISP)-certified and provides CTACG & CTASWP member facilities with semi-annual training classes. Classes are offered in both northern and southern California. Access to an on-demand tutorial webinar is also available to compliance group members.

Training classes are designed to highlight the Industrial General Permit requirements and how to implement them. These sessions also provide the opportunity for members to share and discuss which best management practices have been effectively implemented at their sites and the associated costs.

CTA members who join either the CTACG or CTASWP for the first time will receive a 10% discount on their first year of storm water program membership. Current CTACG or CTASWP members can also receive a 10% discount on one year of membership by referring another CTA member facility to enroll in the CTACG or CTASWP for the first time. Current members can refer up to 10 new facilities to receive an entire year’s membership for free!
