site mapSWPPP Design Construction

Phase II of the NPDES Clean Water Act requires a Storm Water Pollution Prevention Plan (SWPPP) for any project that disturbs one acre of soil or more. Once construction plans have been reviewed and approved, a "Notice of Intent" (NOI) is required by law before construction can begin. The NOI provide basic information about the site's drainage characteristics and is a signed promise by the property owner to design and implement a Storm Water Pollution Prevention Plan. The SWPPP once filed must be maintained on the job site until the owner files a "Notice of Termination" (NOT), which states that the individual or entity no longer has interest in the property or the project is complete.

The SWPPP must be adhered to at all times and any modifications due to changes in construction sequence, weather, or new information, must be documented. In addition, there are certain fundamental requirements common to all SWPPPs such as training, key personnel identification, emergency response measures, and regular or special site inspections and maintenance of "Best Management Practices" (BMPs).

Because liability is soaring for noncompliance, builders are paying closer attention to storm water pollution prevention as a key element of their construction projects. Financial penalties can range from several thousand dollars per day to tens or hundreds of thousands of dollars per incident. Civil and criminal suits filed by individuals and special interest groups can seek even more in damages. Jobs can also be shut down for failing to comply with water quality laws, which can cost thousands per day in lost productivity, interest or liquidated damages.

Thunder Mountain Enterprises, Inc. is the foremost SWPPP designer in Northern California, measured in experience, quality and integrity. No one combines the arts and sciences of civil engineering, landscape construction, biotechnology, and erosion & sediment control technology like we do, to allow construction and environment to come together. Over ten years ago, our "Certified Professional in Sediment & Erosion Control" (CPESC) was among the first thousand (#808) in the world to earn this credential, and is now one of the most experienced in the business.

Our world class SWPPP designs and consulting experiences include hundreds of California construction sites, including housing developments, commercial developments, public schools, hospitals, California Department of Forestry, U.S. Postal Service, and many others.

Training Services
Thunder Mountain Enterprises, Inc. offers a wide range of technical services. We are not academics. We go to where the work is, and provide dozens of "tail gate training" sessions each year on job sites with hands-on demonstrations using down to earth language that a contractor's or subcontractor's field crews can appreciate and understand. We also work closely with the regulatory community and include them in our training sessions whenever possible, in both formal class room sessions and in the field, to promote understanding, and break down the psychological barriers and misinformation that often exists.
