EcoScience Corporation - Stormwater Experience

STORMWATER EXPERIENCE

INTRODUCTION

The 1972 Clean Water Act provided for the issuance of permits through the National Pollution Discharge Elimination System (NPDES) program to regulate the discharge of pollutants into receiving waters. The U.S. Environmental Protection Agency is the federal agency responsible for issuance of NPDES permits to protect water quality. Discharges of stormwater run-off from construction sites which disturb five or more acres of land must be covered by an NPDES permit. In North Carolina, the Division of Water Quality (DWQ) is responsible for the NPDES program. The decision to issue a stormwater permit is based on the development and implementation of a Stormwater Pollution Prevention Plan (SPPP). The SPPP process is expected to involve six major phases including: 1) site evaluation and design development; 2) assessment; 3) control selection and design; 4) certification and notification; 5) construction/implementation; and 6) final stabilization/termination.

ECOSCIENCE QUALIFICATIONS

The experience of EcoScience Corporation (ESC) personnel in the area of stormwater planning and NPDES permitting includes: preparation of SPPPs, North Carolina Global Transpark (NCGTP) Comprehensive Stormwater Plan, and water quality sampling.

Preparation of Stormwater Pollution Prevention Plans
EcoScience personnel have been involved with the preparation of numerous SPPPs for industrial and commercial clients in North Carolina, Kentucky, Michigan, and Ohio. Development of SPPPs involve several phases of activities, including planning and organization, assessment, best management practices selection, plan design, implementation, and ongoing site evaluation. Clients have included: Amerimark Building Products (N.C. and Ohio); World Source Coil Coating (Ky.); Wolverine Coil Coating (Mich.); Directional Inc. (N.C.); ALSCO Aluminum Products (N.C.); and Mebane Packaging Corporation (N.C.).

North Carolina Global TransPark Comprehensive Stormwater Plan
NCGTP is a 15,726-acre complex in eastern North Carolina targeted for onsite commercial packaging and shipping to accommodate international trade opportunities for the state and region. ESC personnel have developed a conceptual stormwater master plan for the complex. This conceptual plan forms the basis for ongoing planning and eventual permitting under the NPDES program, utilizing the MS-4 municipal application process as the template. The end result will be an NPDES permit under which NCGTP will assume responsibility for stormwater permit review of individual tenants. The plan will cover the entire 15,726-acre site. ESC has coordinated extensively with the DWQ, Stormwater Unit, to develop this program. The NCGTP stormwater management plan will include structural stormwater controls, education and training programs, monitoring/reporting protocols, source tracking procedures, and public interest programs. Because of project-specific needs, the plan will be innovative, creative, and flexible.

Water Quality Sampling
EcoScience personnel have been involved in water quality sampling for a variety of project purposes. Samples have been analyzed in situ for pH, turbidity and basic nutrients and have been forwarded to laboratories for detailed analysis. Clients have included NCGTP, TexasGulf and Amerimark Corporation.
