FINAL MITIGATED NEGATIVE DECLARATION PROJECT: LEAD AGENCY: ASIAN CLAM CONTROL PROJECT, EMERALD BAY STATE PARK California Department of Parks and Recreation AVAILABILITY OF DOCUMENTS: available for review at: The Initial Study for this Mitigated Negative Declaration is Sierra District Headquarters California Department of Parks and Recreation 7360 West Lake Blvd. Tahoma, CA 96142 Northern Service Center California Department of Parks and Recreation One Capitol Mall, Suite 410 Sacramento, CA 95814 PROJECT DESCRIPTION: The California Department of Parks and Recreation (DPR) proposes to treat and control Asian clams (Corbicula fluminea) in Emerald Bay State Park in Lake Tahoe, California. The following is a brief summary of proposed work: Strategically place EPDM rubber pond liner (or similar) material over the benthic substrate (benthic barriers) where an Asian clam (AC) population occurs on the lake floor within Emerald Bay State Park. This infestation increased in size by 40% between 2009 and 2011. Employ other treatment methods such as suction removal or substrate freezing in areas where placement of rubber benthic barriers has limited success. Insertion of material such as straw under the barriers will also be tested to determine if these supplements help to decrease dissolved oxygen under the mats to more effectively treat the AC. Conduct pre- and post-project characterization of the benthic invertebrate community to document effectiveness of AC treatment and impacts on other benthic invertebrates. A copy of the Initial Study is attached. Questions or comments regarding this Initial Study/Mitigated Negative Declaration may be addressed to: Dan Shaw California State Parks Sierra District Resources Office P.O. Box 16 Tahoe City, CA 96145-0016 E-mail Address: dshaw@parks.ca.gov Include “Asian Clam Control” on the subject line Fax Number: 530/581-5849
Pursuant to Section 21082.1 of the California Environmental Quality Act, the California Department of Parks and Recreation (DPR) has independently reviewed and analyzed the Initial Study and Draft Mitigated Negative Declaration for the proposed project and finds that these documents reflect the independent judgment of DPR. DPR, as lead agency, also confirms that the project mitigation measures detailed in these documents are feasible and will be implemented as stated in the Mitigated Negative Declaration. _________________________________________ Acting District Superintendent __________________ Date _________________________________________ Environmental Scientist __________________ Date Asian Clam Control Project IS/MND Emerald Bay State Park California Department of Parks and Recreation 29
