John L. Hunter and Associates has been conducting stormwater inspections and public outreach activities for our municipal clients since the outset of the NPDES Programs. The municipal stormwater programs have been developed, modified, and implemented in compliance with the Regional Board’s guidelines and requirements. The levels of service have been tailored to the specific needs of the individual cities. Our services include:
Our site visit program begins with an analysis of City and County records to help set up a database of businesses in a jurisdiction with known potential for contributing to stormwater pollution. These businesses are then inspected and evaluated for possible stormwater impact and illicit connections to the stormwater system. JLHA performs inspections of stormwater critical source (Tier 1 and Tier 2) sites including: restaurants, auto facilities, manufacturing facilities, and oil refineries (over 15,000 completed).
When violations are observed or reported by citizens in the community, every effort is made to resolve the situation quickly in a non-adversarial manner. JLHA can support the City staffs with the issuance of Warning notices, Notices of Non-Compliance and Notices of Violations. This augments the City’s existing code procedure enforcement. Any legal action is typically coordinated with the City Attorney’s staff with JLHA support.
To help cities comply with their NPDES stormwater permits, annual inspections (more frequent if necessary) are made at construction sites. These sites are typically those over one acre or at smaller sites where problems have been reported. The inspections check on the effectiveness of the BMPs to control sediment, and other construction related materials.
JLHA conducts plan reviews of new development sites to determine if proposed locations and size of treatment systems (berms, sandbags, sediment traps, filters, vegetative swales, etc.) meet regulatory standards. Included in the plan checks are size comparisons of the proposed treatment systems to the land surface and potential rainfall, to ensure that the systems would have sufficient capacity to adequately remove pollutants from the stormwater runoff.
Public Agency Stormwater Management Practices
Stormwater Pollution Prevention Plans (SWPPP) and Stormwater Monitoring Plans (SWMP) have been developed and implemented for municipal facilities such as: corporate yards, airports, landfills, and transfer stations (and many industrial facilities). JLHA conducts annual or more often if appropriate, inspections that are a “self” assessment of city facilities to measure the level of compliance with the NPDES permit. These assessments check for: 1. Proper vehicle and equipment washing practice, 2. Proper storage of materials (canopies, berms, etc.), and 3. Good general housekeeping practices. Where required, annual permit implementation status reports are prepared for submittal to the Regional Board.
Complaint Response and Surveillance
Surveillance: JLHA inspectors become familiar with the characteristics of each day. Several times each year, both in dry and wet weather, inspectors make random drive by inspections of hot spots in the City and any observed illicit discharges are followed up through the enforcement program.
Complaint Response: Cities often receive a diverse number of complaints from a variety of sources including: concerned citizens, city staff, local officials, etc. JLHA staff can be called upon to assess the situation and work with the responsible party, to:
1. Stop the discharges
2. Contain what has been released
3. Clean up residue
4. Take steps to prevent possible re-occurrence.
