  • $250,000 Proposition 1 grant award to prepare a Program Environmental Impact Report (PEIR) that assesses the potential environmental impacts of implementing a discretionary well permitting program developed by JJ&A, the first in the state to be aligned with the Sustainable Groundwater Management Act (SGMA). The PEIR included development of a county-wide hydrologic model to aid in the evaluation of impacts related to drawdown, subsidence, surface water depletion, and groundwater-dependent ecosystems. The PEIR was recently adopted, and will help to streamline the well permitting process as well as providing important data to help inform ongoing groundwater sustainability planning efforts by the local Groundwater Sustainability Agencies (GSAs): Stanislaus County.
  • $500,000 Proposition 1 grant successfully obtained from the State Water Resources Control Board for the preparation of a Storm Water Resource Plan: City of Modesto and Stanislaus County.
  • $2 million Proposition 1 grant award from the State Water Resources Control Board to perform a Remedial Investigation/Feasibility Study to identify, prioritize, and design alternatives to address arsenic, nitrate and uranium impacts to the City’s groundwater supplies. The project evaluates the effectiveness of well-field modification and operating strategies, managed aquifer recharge, aquifer storage and recovery and other strategies to improve aquifer water quality, increase water supply resilience, facilitate recharge projects, and decrease long-term treatment costs: City of Modesto.
  • Wetlands Classification Exclusion for Unlined Wastewater Treatment Pond, San Francisco Bay Area, Eliminating Wetland Mitigation and Restoration Requirements and Resulting in Estimated Savings $10M-$15M : SF District, US Army Corps of Engineers.
  • Title 27 Landfill Engineered Alternative to 5’ Waste Separation, Northern California, Resulting in Estimated Savings of $5M : RWQCB – Central Valley.
  • RCRA Corrective Action Consent Agreement Negotiations Creating Distinct Areas of Concern with Additional Separation by Soil and Groundwater (Central and Northern California) Allowing Progressive Cleanup of Site Areas for Reuse/Redevelopment and Reduced Compliance Portfolio:  DTSC – Sacramento,  DTSC – Berkeley, RWQCB – Central Coast.
  • Facilitation Expediting RCRA Corrective Action Projects for Completion of Corrective Action through Use of RCRA FIRST Tools: DTSC – Berkeley; DTSC – Sacramento.
  • RCRA Clean Closures with Facility Wide Impacts Eliminating Post-Closure Permit Path Resulting in Estimated Savings of $5M-$7.5M/site: DTSC – Berkeley; DTSC – Sacramento.
  • RCRA Permit (operating and post-closure) Requirement Reductions Resulting in Lower Annual Facility Operating Costs (estimated range of $100K K/year for 30 year permits) and Reduced Compliance Portfolio: DTSC – Cypress; DTSC – Berkeley, DTSC – Sacramento, RWQCB – San Francisco Bay Area.
  • Health and Safety Code Hazardous Waste Treatment System Permit Exemption Path for Groundwater Cleanups (multiple California sites), Resulting in Expedited Schedules (by elimination of permitting process time delays), Elimination of Permit and Associated Compliance Requirements which Reduced Project Costs and Reduced Compliance Portfolio.
  • JJ&A has completed an NCP compliant investigation and clean up of a 20-acre former heavy manufacturing facility in Northern California. Multiple remedial actions were implemented under a Federal Consent Decree and Water Board CAO including excavation of source areas; in-situ treatment for hexavalent chromium and VOCs; and on-going pump and treat for remediation of recalcitrant compounds. The Site was recently sold and has current commercial tenants with redevelopment in progress for additional industrial/agricultural tenants.
  • Integration of soil remediation with landscape restoration/redevelopment to meet remediation objectives, complete CEQA, and expedite remediation/restoration for enhanced public use, and protection of Bay water quality and identified special status species: Former Power Plant, San Francisco Bay Area.
  • Completion of site remediation allowed for beneficial reuse as commercial or public property. Phased sampling approach reduced the number of locations where drilling was required resulting in $100,000 savings for the client: Former Power Plant, Central Valley, California.
  • Design and implementation of a program-wide efficiency program that reduces costs, increases quality and promotes sustainability: Land Conservation Commitment Program, 30+ locations, Northern California.
