  • 1. Medlin & Associates, Inc. Acoustical Consultants Statement of Qualifications Water and Power P.O. Box 130941 Carlsbad CA 92013-0941 (760) 930-6515 www.medlin-acoustics.com
  • 2. Medlin & Associates, Inc. Acoustical Consultants Project Spotlight: Electric Generating Station Los Angeles Department of Water and Power Haynes Generating Station Noise Assessment Medlin & Associates, Inc. performed a survey of noise emissions from the LADWP Haynes Generating Station in Long Beach, California, analyzing individual machine contributions as well as establishing the overall plant noise impact on the community. Our services included: • Spectral analysis of individual machinery noise emissions • 24-hour community noise monitoring • Establishment of plant noise impacts vs. other community noise (e.g. traffic) • Assessment of municipal code compliance • Recommendations to reduce machinery noise impacts Benefit: Findings assisted LADWP in planning construction of new generating equipment with due consideration given to local noise ordinance compliance and minimizing community impacts.
  • 3. Medlin & Associates, Inc. Acoustical Consultants Project Spotlight: Compex Water Storage EIR Los Angeles Department of Water and Power SilverLake and Headworks Draft EIR Medlin provided the Technical Noise Study for the SilverLake Reservoir Complex Storage Water Replacement and Headworks Hydroelectric Generating Plant. Our services included: • 24 hour noise measurements on the SilverLake and Headworks sites • Ambient noise measurements in the communities • Measurements at a similar Hydroelectric Plant • Evaluation of Operational and Construction Noises • Recommendations to reduce community noise impacts • Generation of the Noise Technical Report • Coordination with LADWP staff 75 70 65 60 dBA 55 50 45 40 2:23 PM 3:23 PM 4:23 PM 5:23 PM 6:23 PM 7:23 PM 8:23 PM 9:23 PM 10:23 PM 11:23 PM 12:23 AM 1:23 AM 2:23 AM 3:23 AM 4:23 AM 5:23 AM 6:23 AM 7:23 AM 8:23 AM 9:23 AM 10:23 AM 11:23 AM 12:23 PM 1:23 PM 2:23 PM 3:23 PM Time Headworks Generator Site: CNEL 68 Benefit: Our CEQA Technical Noise Impact Study determined that the construction and operation of the project would result in significant noise impacts. Medlin recommended noise mitigation measures to reduce the impact on the adjacent communities.
  • 4. Medlin & Associates, Inc. Acoustical Consultants Project Spotlight: Pipeline Construction EIR Los Angeles Department of Water and Power River Supply Conduit Improvement - Upper Reach Medlin & Associates, Inc. performed the technical noise study in support of the LADWP RSCI Upper reach EIR. Our services included: • Establishing ambient noise levels at sensitive receivers along the construction route • Modeling noise emissions from open-trenching construction activity • Determining airborne noise impacts from open--trenching pipeline construction • Estimating groundborne vibration impacts from tunnel-boring at residential and sensitive commercial receivers • Recommending mitigation measures • Assessment of municipal code compliance and significance of impacts Benefit: Findings furthered LADWP's efforts in modernizing the Los Angeles water supply system.
  • 5. Medlin & Associates, Inc. Acoustical Consultants Project Spotlight: Gas Turbine/Generators Frank R. Bowerman Landfill Gas Electric Generation Project As part of an overall CEQA study, Medlin & Associates, Inc. projected noise emissions from a planned gas-turbine electric generation facility, at the Frank R. Bowerman landfill in Irvine, California. Our services included: • Establishing ambient noise levels at sensitive receivers • Determining composite plant noise emissions from equipment manufacturer data • Projecting noise levels at nearby receivers, including the effects of surrounding topography • Assessment of municipal code compliance and determination of significant impacts existing flare and LNG facility Frank R. Bowerman Landfill ~3400 ft existing residential development Benefit: Findings helped pave the way to installation of new alternative-energy electric generation facility, fueled by natural gas created as a byproduct of landfill decomposition. P.O. Box 130941 Carlsbad CA 92013-0941 (760) 930-6515 www.medlin-acoustics.com
  • 6. Medlin & Associates, Inc. Acoustical Consultants Project Spotlight: Pipeline Construction CEQA Otay Water District Jamacha Road 36" Potable Water Pipeline MND Medlin & Associates, Inc. conducted a technical noise study in support of a mitigated negative declaration for construction of the Otay Water District's Jamacha Road 36" Potable Pipeline. Our services included: • Establishing ambient noise levels at sensitive receivers along the construction route • Modeling noise emissions from open-trenching construction activity • Determining impacts at sensitive receivers • Recommending mitigation measures • Establishing limitations on blasting Trenching & Pipelaying excavator dump trucks welding truck crane Benefit: Our CEQA Technical Noise Impact Study determined that the construction would result in no significant noise impacts with mitigation in place.
