STATEMENT OF WORK

On-site Hypochlorite Generation System Replacement

I GENERAL INFORMATION

A. Introduction

The Western Fisheries Research Center (WFRC) located in Seattle, Washington.

The WFRC carries out research and provide technical assistance to support the best possible stewardship of the Nation's natural resources, emphasizing fish populations and aquatic ecosystems of the West. The WFRC has a 50 year history of excellence in fisheries disciplines and are leaders in the field of molecular and microbiology within the U.S. Geological Survey (USGS). The WFRC addresses the unique issues of large western river systems such as the Columbia, and the challenges faced by desert aquatic systems and their threatened or endangered fish species.

The WFRC's Seattle headquarters laboratory is located at Sand Point on the shores of Lake Washington. The wet laboratory draws large quantities (approximately 500,000 gallon a day) of fresh water from the lake for aquatic experiments. This laboratory, completed in 1994 at a cost of 10 million dollars, replaced a World War II era U.S. Navy building in which the WFRC had conducted fishery research for nearly three decades. The new laboratory provides WFRC scientists with a world-class resource unique in the USGS, and the research community.

The WFRC is approximately 60,000 square foot facility of which approximately 10,000 square feet are dedicated to the wet laboratory. At any given time the wet laboratory hosts 20 to 30 long and short term live fish experiments all of which rely on high quality process water.

B. Background The WFRC - Seattle Laboratory relies on the Ultra-Violet lighting, chlorination and dechlorination systems to treat process water effluent. It is critical that all systems work properly due to the types of aquatic experiments and the fact that the effluent water returns to Lake Washington. The Seattle Laboratory draws a large quantity of water (up to 400 gpm) from Lake Washington. This water is UV treated and sent through the Wet Lab for aquatic experiments. Once the water is sent to drain the on-site chlorination system treats the water in the underground holding tank and then is dechlorinated using the SO2 treatment system. Without proper operation of these systems the Center could inadequately treat water to the USGS aquatic experiments or send untreated water back to a wetland near Lake Washington potentially impacting native species. Treating the effluent water is a key component to the process of providing high quality lake water to all live fish experiments in the wet laboratory.

Ultra-Violet (UV) lighting and effluent treatment are a key component to providing high quality lake water to all live fish experiments in the wet laboratory. The existing on-site hypochlorite generation system has become obsolete and is need of replacement to ensure proper treatment of effluent and for optimal operations.

The contractor must be very familiar with our operations and the need to have zero impacts to critical aquatic experiments. The contractor will work directly with scientist at the WFRC to ensure downtime is kept to a minimum and performed during the minimal potential impact to experiments. This may require waiting to begin until experiments are complete or to work in a window of opportunity to keep the impact aquatic experiments to a minimum. The service provider will need to provide all engineering services, labor, and work directly with the USGS maintenance staff.
