Empire Mine Historic Park Environmental Services
Grass Valley, California

The Empire Mine State Historic Park (Empire Mine) site is undergoing investigation and remediation for metals contamination from historic mining practices. The goal is to preserve the historical and natural resources at the mine for current and future generations while remediating chemical hazards.

Burleson completed task orders for the California Department of Parks and Recreation at the Empire Mine in Grass Valley. The tasks included:

  • Biological and cultural monitoring during summer remediation and construction projects at the Red Dirt Pile
  • Preparing and submitting the 2006-2007 Annual State Stormwater Report for Industrial Activities
  • Updating the facility Storm Water Pollution Prevention Plan (SWPPP)
  • Preparing monthly status reports for the National Pollutant Discharge Elimination System (NPDES) Report of Waste Discharge from the Magenta Drain Portal effluent

Burleson conducted the 2007 biological and cultural surveys for endangered and special-status plant and wildlife species prior to removal of trees and construction of a cap at the Red Dirt Pile. Burleson also provided training and ongoing biological and cultural monitoring during the 3‑month duration of construction.

Burleson prepared the monthly NPDES self-monitoring reports for the Magenta Drain Tunnel portal discharge, a point source regulated by waste discharge requirements (WDRs) issued in 2006. The monthly report included an evaluation and discussion of the monthly analytical data and weekly field measurements collected from the discharge point and two background (receiving water) locations as compared to the permit effluent limits.

Burleson prepared the Annual Stormwater Report for the 2006-2007 seasons. Stormwater from areas of concern flows to Little Wolf Creek. This task included compiling and reporting the 2006-2007 yearlong monthly stormwater analytical data and visual observations from 35 sample locations, conducting a review of the Industrial SWPPP for revisions, and evaluating the effectiveness of the current best management plans (BMPs) for controlling pollution in the stormwater flows.

Burleson also:

  • Prepared the 2007-2008 SWPPP, added sample locations, evaluated observed pollutant concentrations by comparing data to US EPA benchmark and water quality objectives for Little Wolf Creek
  • Inspected and documented effectiveness of BMPs at the Service Yard, Mine Yard, Red Dirt Pile, Stamp Mill, Cyanide Plant, Sand Dam, Adit Tunnel, and Spoils Stockpiles
  • Proposed new long-term BMPs

Client Satisfaction

"Burleson Consulting was excellent to work with and very professional. They assembled a top-notch team of experts to study and propose solutions to the water supply challenges at Sutter National Wildlife Refuge. The communication was excellent throughout the project. This included project staff, contracting personnel, and interested stakeholders. As a result, the project was completed on time and on budget. I would not hesitate to use or recommend Burleson Consulting in the future."Kevin Clancy, Project Manager – United States Bureau of Reclamation

"Burleson provided exceptional services under this contract. Because of their successful work, they were awarded a $7M follow-on IDIQ contract in 2014, that also encompasses biological monitoring at former Fort Ord. They have consistently improved their plant material collection and propagation techniques and pass the savings onto the federal government. Burleson is a valuable team member on Fort Ord and I feel that they are true stewards of the environment." William K. Collins, BRAC Environmental Coordinator, US Army Corps of Engineers

"Burleson has been able to work with several government agencies (to include tribal groups and natural resource trustees) and several responsible parties to assist in progressing this site to a stage where technical and agency concerns can be identified and resolved. Strengths – overall and in depth understanding of mine site and CERCLA dynamics. Deficiencies – none. I would not hesitate to use Burleson." Daniel McMindes, USACE Liaison to EPA, US Army Corps of Engineers

"Burleson helped to manage the Sacramento Area Voltage Support Environmental Impact Statement. They came through and were always available during an ‘energy crisis’ in California. I will continue to work with them."Loreen McMahon, Project Manager - California Public Utilities Commission

"We appreciated Burleson’s great work, re: completing the draft EIR on the scheduled date (it was a tremendous task, but they completed it). All of them put a lot of work into it (it was a true team effort). They should all be proud of this accomplishment given the changes and obstacles encountered along the way, and I cannot thank them enough."Glenn M. Shuder, AIA, CFM, Chief Architect - Project Director, SMUD
