Copper solubility curves are used in conducting the complex WER studies. Copper leaching from old pipes is toxic to fish and the amount that may be discharged into streams and rivers is limited by state and federal regulations. |

Nearly every public works project requires permitting. Because Gibbs & Olson specializes in public works projects, we have acquired expertise on the required permits and approvals, their timing, and implementation. We offer as much assistance as needed to obtain permits and approvals Perform water quality analyses, evaluations and consultations (e.g., as part of producing and updating state-required General Sewer Plans) Design innovative construction techniques for crossing of wetlands and/or streams Design hydraulic structures such as spillways, fish ladders, canals, diffusers Assist with providing responses to environmental compliance correspondence from DOE, EPA, and others. For example, we can comment to DOE with regards to NPDES permit conditions, TDML (Total Daily Maximum Load) studies and other requirements Prepare Water Effects Ratio (WER) studies in compliance with DOE guidelines Prepare Clean Metals Studies in compliance with DOE guidelines Develop Quality Assurance Project Plans (QAPP) in compliance with DOE guidelines to ensure high quality data collection methodologies for water sample testing Conduct surface water restoration projects

Environmental specialist on staff 56 years of experience with public works projects has allowed us to acquire unparalleled expertise on the required permits and approvals, their timing, and implementation. We’ve completed hundreds of successful permit applications and approval requests for clients Experience with obtaining multiple permits per project. For example, we completed a major utilities upgrade for the City of Chehalis (2003) in which we were responsible for obtaining a total of 14 permits and approvals Numerous good relationships with regulatory agency staff. These relationships aid in the environmental permitting and compliance process Engineers on-staff trained and experienced in water chemistry, microbiology, hydrology, and hydraulics Experience with both simple and complex water quality analyses and enhancement program pilot studies as well as full-scale protocol and testing of unit processes Established relationships with subconsultant firms specializing in geology, hydrogeology, toxicology, environmental compliance, water and natural resources, environmental investigations, and remediation Involvement with surface water quality enhancement projects in the Cities of Longview and Woodland have resulted in improved aesthetics, enhanced recreation and enhanced (or provided the opportunity to enhance) aquatic environments for fish in both Lake Sacajawea (Longview) and Horseshoe Lake (Woodland) Development of one of the first Quality Assurance Project Plans (QAPP) to be approved by Washington State Department of Ecology. These plans outline strict requirements to be followed when conducting sampling and testing programs for environmental projects Gibbs & Olson conducted some of the first Water Effects Ratio (WER) studies in the State of Washington We have unparalleled experience in working with discharge limitations imposed by Total Maximum Daily Load (TMDL) studies prepared by the Department of Ecology
