Storm Water Management
Dodson & Associates, Inc. has been
involved in the storm water pollution arena since the beginning years of
NPDES regulations, both in permitting and in education.
We have provided training and compliance support to three state
Departments of Transportation: the Arizona DOT, Hawaii DOT, and New Mexico
DOT to assist them with NPDES compliance. In each case, we were asked to assist the DOT in developing
strategies to implement Best Management Practices (BMPs) that would allow
them to operate their systems in compliance with their municipal discharge
permits.
The projects detailed below, as well as
our experience teaching NPDES seminars, has given us an excellent
understanding of Phase I, Phase II and Industrial Storm Water program
preparation.

Example Projects
City of Port St. Lucie Storm
Water Master Plan
Port St. Lucie, Florida
Compliance with
the upcoming NPDES Phase II regulations for small municipalities, and the
State of Florida’s adaptation of these regulations to a state-specific
permit. The city of Port St.
Lucie will be required to comply with federal and state regulations
regarding storm water discharges from municipal outfalls and outfalls from
municipally-owned industrial facilities and construction activities on
March 10, 2003. The state is
in the process of developing a generic permit for small municipalities
that will include a requirement to develop a city-wide Storm Water
Management Plan (SWMP), submit annual reports on the status of
implementing the SWMP, and submit a Notice of Intent (NOI) in order to
apply for the permit. The
entire project includes the following:
Ø
Preparation of the application for the NPDES
General Permit to be submitted to the Florida Department of Environmental
Protection (FDEP).
Ø
Preparation of the permit application and
production of a complete Storm Water Management Plan.
Ø
Review of the code of ordinances and recommend
changes in order to assist with preparing the SWMP.
Ø
Research of the current state of storm water
enforcement within the city and provision of materials relevant to any
necessary changes including recommendations for cross-training between
city departments and checklists for inspectors.
Ø
Recommendation on staffing and fee structure and
budget to implement the program.
Corpus Christi Storm Water Master
Plan
Corpus Christi, Texas
Dodson & Associates, Inc. has been chosen as part of a team of consultants
to assist the City of Corpus Christi in development of a final storm water
criteria and design manual.
The existing Master Storm Water Master Plans were developed at different
time periods as the City expanded such that the drainage design parameters
are not consistent between areas.
Phase One of this project includes development of engineering and
community (level of protection)
criteria to reflect soil conditions and topography.
The result will be a Storm Water Criteria and Design Manual.
Phase Two includes development of a comprehensive Master Storm
Water Plan for the City of Corpus Christi using the Criteria and Design
Manual from Phase One. Phase
Three is an evaluation of individual drainage systems, prioritized based
on severity of deficiency, including specific drainage systems that have
been identified either by observation or preliminary study as exhibiting
drainage problems. Dodson &
Associates, Inc. is also assisting the City of Corpus Christi with
complying with the revised NPDES Phase II requirements that are soon to be
issued in the state of Texas.
Another major portion of Dodson’s contract includes floodplain mapping of
the area using GIS applications, and conducting a training seminar for
city personnel on the use of GIS software.
NPDES Industrial Storm Water
Permit Applications
Over 100 Facilities in 13 States
Dodson & Associates, Inc. provided a
broad range of services for Southdown, a Fortune 500 company that is a
fully integrated manufacturer of cement and concrete products.
These services all related to storm water discharges and EPA
compliance activities. The
services included site inspections, permit preparation, employee training,
demonstration of storm water sampling, recommendation of remedial and
storm water management measures, preparation of storm water pollution
prevention plans, field testing, presentation of expert testimony at EPA
hearings, and many other related services.
Many of the Southdown facilities are
located in southern California, including a large number of Transit-Mix
ready mix concrete batch plants located throughout Los Angeles and Orange
County areas, the large sand and gravel mining operation located in Azusa,
the Rho-Chem hazardous waste handling facility in Inglewood, and the
Southwestern Portland Cement plants and associated limestone quarries
located in and around Victorville.
Dodson & Associates, Inc. initially
prepared parts I and II of a group permit application for the concrete
ready-mix batch plants, but when the State of California issued its
general permit for industrial storm water discharges in 1992, the group
permit was amended and these facilities were covered under the California
general permit.
NPDES Audit
Idaho Falls, Idaho
An evaluation of the Idaho National
Engineering and Environmental Laboratory (INEEL) storm water program in
order to compare the program to other storm water programs in the United
States. The evaluation would
then be used to determine future scope and direction of the INEEL storm
water program and to apply for appropriate coverage under new permits
based upon this future scope.
Recommendations were made for how their storm water program needs to be
planned and carried out over the next several years.
Storm Water Pollution Prevention
Plan – Austin Research Boulevard Site (AURB)
Austin, Texas
The completed Storm Water Pollution
Prevention Plan (SWPPP) was for the 3M Research Boulevard site in Austin,
Texas. The site is located in
north central Austin, along Research Boulevard (US Highway 183), near the
border of Travis and Williamson counties.
This SWPPP was prepared to identify and detail the actions the
facility must take to prevent the contamination of storm water runoff.
The two major objectives of the SWPPP were to help identify the
sources of pollution that affect the quality of industrial storm water
discharges and define and ensure the implementation of best management
practices that would reduce pollutants in industrial storm water
discharges.
Harris County Flood Control
District Sediment Control
Harris County, Texas
Dodson & Associates, Inc. has been
involved with the Harris County Flood Control District (HCFCD), in
Houston, Texas, as they have developed a Storm Water Management Plan as
part of the NPDES Phase I permit requirement and have provided services to
assist them with their plans.
Our GIS specialists developed a database of soil erosion factors in each
of the 22 major watersheds within Harris County, then applied the factors
to a GIS-based map of Harris County, Texas, to assist the District in
determining erosion-prone areas and developing measures to reduce the
on-going problem. The
information is useful for selecting appropriate best-management practices
for construction sites at different locations throughout the county.
It also leads to a more objective way of comparing the effects of
different projects and different project approaches, including the
selection of Best Management Practices (BMPs) for HCFCD and Harris County
public works projects.
