Stormwater Compliance (Construction and Industrial)

VESTRA has prepared hundreds of Construction and Industrial Stormwater Pollution Prevention Plans (SWPPPs) and Erosion Control Plans for clients under the Industrial and Construction General NPDES permit requirements of the State of California.

Construction SWPPPs are required for project sites disturbing one acre or more of soil and generally focus on establishing the Best Management Practices (BMPs) that will be employed to prevent sediment from leaving the site during construction activities. Plans also include monitoring activities to gauge the efficacy of the BMPs. For construction, our Engineers have extensive experience in designing and implementing these plans, conducting site inspections, performing required sampling, and preparing the necessary documentation and reports. Our work includes both the General Construction Permit and the special Caltrans requirements and provisions.

Industrial SWPPPs are required for sites covered by the State Industrial General Permit, including manufacturing facilities, oil and gas/mining facilities, hazardous waste treatment, storage and disposal facilities, landfills, transportation facilities, and sewage or waste treatment works. Industrial SWPPPs focus on pollutants that may be present onsite and describe activities employed to prevent those pollutants from leaving the site. Our staff include one Trainer of Record, and two Qualified Industrial Stormwater Practitioners (QISPs) under the new Industrial General Permit. We have assisted hundreds of clients in preparation of SWPPPs, compliance sampling, reporting, development of site-specific sampling and evaluation strategies, and design of treatment systems. Our work has included activities under the Clean Water Act (CWA) Section 505 citizen litigation provisions and commonly results in reduced settlements and shortened oversight periods. Samples of the industries we have served include marinas, sawmills, aggregate and mineral processing facilities, dairies, confined aquatic feeding operations, log yards, trucking facilities, municipalities, counties, landfills, transfer stations, and material recovery facilities.

Waste Containment and Treatment

Whether it is a dairy manure pond, agricultural wastewater pond, or landfill, we can design and permit your containment solution. Our team members are experienced in all Title 27 requirements for landfills and impoundments, liner and cover designs, construction plans, drainage system designs, stormwater containment, and Notices of Non-Applicability (NONAs) under the Industrial General Permit and can also supply Construction Quality Assurance and related Surveying. We are also NRCS Technical Service Providers and have significant experience in the NRCS requirements for lining and design of agricultural containment systems.

Remedial Design and Treatment

Our team has conducted remedial activities in accordance with the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA); National Contingency Plan (NCP); Resource Conservation and Recovery Act (RCRA); as well as the Department of Toxic Substances Control (DTSC) and Regional Water Quality Control Board (RWQCB) guidance. We have also conducted cleanup work at underground and aboveground hydrocarbon sites and work diligently to obtain closure in the shortest time possible.

Our Remedial Alternatives Include:

  • Soil Excavation and Removal

  • Ozone Injection
  • Sulfate-Reducing Bioreactor
  • Wetlands Treatment
  • Natural Attenuation

Conservation Easements
& Mitigation Banking

An increasing trend in rural land management is the initiation of Conservation Easements and the development of Mitigation Banks. Most Conservation Easements require a Remoteness Determination/Mineral Assessment Report. The purpose of this type of study is to determine if the property is in accordance with Federal laws governing the tax deductibility of Conservation Easements in which the ownership of the surface estate and mineral interests has been separated. Many of these studies have been conducted concurrently with a Phase I Environmental Site Assessment in order to save our clients time and money, as many aspects of both studies are similar in content

Our goal is to assist with the establishment of local mitigation banks so that local dollars stay local and any loss of Northern California wetlands are compensated with the preservation and establishment of local wetlands. We are currently assisting with the establishment of a mitigation bank in Tehama County and have assisted with the development and maintenance of other mitigation banks in Shasta County.

Property Transfer Due Diligence

We have completed hundreds of Real Estate Site Evaluations for clients who wish to buy, sell, or transfer properties. Prior to buying or developing a property, it is important to identify any potential risks, since under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), a buyer, lessor, or lender may be held responsible for remediation on a property, even if a prior owner caused the initial contamination. All Property Transfer Evaluations are conducted pursuant to American Society for Testing and Materials (ASTM) standards. The goal of the site assessments is to identify environmental conditions in connection with the property, to the extent feasible, which may pose a future environmental liability. Our work includes ASTM Phase I and Phase II Environmental Site Assessments, Environmental Liability Appraisals, Environmental Transaction Screens, Feasibility and Cost-Benefit Analyses, Historical and Regulatory Reviews (current and past site activities), Conservation Easement Documentation, and detailed Site Characterization and Remediation. VESTRA has conducted these for commercial, multi-residential, industrial, and agricultural properties ranging in size from less than one acre to over 30,000 acres. One of our areas of specialization is working with large rural properties.

An increasing trend in rural land management is the initiation of Conservation Easements and the development of Mitigation Banks. Most Conservation Easements require a Remoteness Determination/Mineral Assessment Report. The purpose of this type of study is to determine if the property is in accordance with Federal laws governing the tax deductibility of Conservation Easements in which the ownership of the surface estate and mineral interests has been separated. Internal Revenue Code § 170(h)(5)(B)(ii) states that, for such donations, the conservation purpose will be considered to be perpetually protected if the probability of surface mining on the property is so remote as to be negligible. Federal Treasury Regulations 26 CFR 1.170A-14(g)(4) further state that a deduction will not be denied in the case of certain methods of mining that may have limited localized impact on the real property but that are not irremediably destructive of significant conservation interests.

Our goal is to save our clients time and money, conducting investigations and assessments in a cost-effective manner that fulfills all requirements for the property transfer.

Mine Remediation Expertise

VESTRA staff has been involved in several projects to address metals contamination at mine sites beginning in early 1990. These studies led to a number of ongoing mine remediation projects throughout California. Based on this experience, VESTRA has developed significant expertise in the following mine remediation related areas:

  • Site characterization
  • Portal and tunnel rehabilitation
  • Bulkhead seal installation
  • Waste rock consolidation and capping
  • Pilot treatment systems
  • Full-scale treatment systems
  • Regulatory permitting and compliance

Key steps in the remediation process include source identification, source control and reduction, and treatment of residual acid rock drainage (ARD). VESTRA has designed and supervised the contruction of more than 10 anaerobic treatment systems to increase the pH and remove dissolved metals from ARD. The capacity of these systems typically ranges between 1 gallon per minute (gpm) and 50gpm, and the average metals reduction exceeds 95 percent.

Our success rate with passive treatment systems is outstanding and we have saved our clients millions of dollars in remediation costs. Our goal is to stay ahead of our competition by offering cost-effective, cutting-edge solutions.
