Projects

Air Quality and Climate Change Impact Assessment (AQCCIA)
Sespe Consulting prepared an air quality and climate change impact assessment (AQCCIA) for an EIR for a large construction materials company. The proposed project was a heavily contested modification to the CUP for a mine located in Los Angeles County and the South Coast Air Quality Management District’s (SCAQMD) jurisdiction. As part of the AQCCIA, Sespe prepared criteria pollutant and greenhouse gas emission inventories for the existing project and the proposed modifications. In addition, Sespe modeled localized criteria pollutant and health risk impacts using EPA’s AERMOD model and CARB’s HARP program. Mitigations were also designed to reduce project impacts to less than significant levels.

After the AQCCIA was finalized, Sespe represented the client in multiple Planning Commission and City Counsel hearings. After a detailed review of the AQCCIA, the SCAQMD stated in a local newspaper article that the study was "well-prepared.”

Air Permitting - Oil Production
Sespe works on air permitting for an oil production facility in Ventura County. A Ventura County Air Pollution Control District (VCAPCD) permit was obtained for number of wells and related production equipment. Sespe worked with the VCAPCD to allow the facility the maximum amount of operational flexibility without exceeding allowable emission thresholds.

Greenhouse Gases (GHG)
Sespe prepared a greenhouse gas (GHG) emissions quantification and tracking system for a large manufacturing facility in southern California. The system calculates GHG emissions from solvent use, stationary fuel combustion, mobile fuel combustion, and electricity usage based on industry standard methodologies. Emphasis was placed on keeping the system simple and easy to use yet providing useful, real-time data. Clearly defined input parameters and graphical output visualizations contributed to the success of the system as a method for tracking and calculating GHG emissions. The client’s parent company was so impressed with they system, they adopted it for all of their U. S. operations.

Greenhouse Gases (GHG) / SB 375
Sespe collaborated with a multidisciplinary team to evaluate SB 375, the California bill aimed at redesigning communities to reduce greenhouse gases. Sespe assisted by tracking regulatory activities at the California Air Resources Board (CARB) and the Southern California Association of Governments (SCAG) and by providing air quality expertise to the team. The Team performed the following tasks:
- Conducted survey of individual city efforts.
- Compared current efforts of individual cities to what may become necessary.
- Monitored and reported on the SB 375 process and related meetings.
- Conducted a series of SB 375 workshops for City Managers and Planners.
- Prepared a whitepaper report detailing recommended compliance strategies.

EHS Support - Mine Site
Sespe provides a variety of environmental, land use, safety, and industrial hygiene management services to a large mining operation in Ventura County. Sespe assists the company, who produces a number of aggregate and specialty sand products, with ongoing compliance support as well as permitting. Specific services provided include:
- Title V air permitting and compliance certifications
- CARB In-Use Off-Road Diesel Vehicle Air Toxic Control Measure (ATCM) support
- CUP condition compliance
- Annual Surface Mining and Reclamation Act (SMARA) inspection and reporting
- Annual Financial Assurance Cost Estimate (FACE)
- WDR and storm water compliance support
- Storm Water Pollution Prevention Program (SWPPP) development.

Hazardous Material / Hazardous Waste Reporting
Sespe assists a large manufacturing company in all forms of hazardous materials and hazardous waste compliance, including reporting and management. Recently, Sespe has successfully prepared the company’s Toxic Release Inventory (TRI) and Biennial RCRA Hazardous Waste Report (Biennial).

The company is required by the EPA to submit a TRI annually for various compounds including metals and solvents. Sespe conducted waste stream calculations to determine the total amount of releases of these chemicals.

The site is also required to detail hazardous waste shipments to the EPA in the Biennial Report. Sespe prepared the required forms for 13 individual hazardous waste streams and assisted the client in submitting them to the EPA.

Spill Prevention, Control and Countermeasure (SPCC) Plans
Sespe has prepared and certified Spill Prevention, Control and Countermeasure (SPCC) Plans for numerous sites including manufacturing, natural resource production, fuel distribution facilities. Sespe has Registered Professional Engineers (P.E.) on staff who can prepare and certify SPCC Plans as required by the regulations.

Construction SWPPPs
Sespe has prepared Storm Water Pollution Prevention Plans (SWPPPs) for dozens of construction sites in California including commercial, residential, and industrial developments. These SWPPPs were developed to meet the requirements of the new General Permit for Construction Storm Water Discharges. Sespe has staff members that can act as a Qualified SWPPP Developer (QSD) as required by the new General Permit.

Industrial SWPPP - Mine Site
Sespe prepared and maintains an industrial SWPPP for a large active mining facility in Ventura County. The SWPPP covers 8 drainage areas, four separate outfalls, multiple industrial operations, and constantly changing terrain. Sespe also assists the facility in filing their storm water annual reports.

Environmental Due Diligence - Lumber Mill
Conducted environmental due diligence (Phase I Environmental Site Assessments) involving three separate ownership properties, entailing almost 45 acres of land. The large lumber mill operation had a complex history that included significant solvent contamination to both soil and groundwater. The contaminated property had undergone remediation and isan active Spills, Leaks, Industrial Cleanup (SLIC) property with oversight provided by the Central Coast Regional Water Quality Control Board. Ongoing monitoring is projected to occur for the foreseeable future.

The client desired to acquire the entire area (all parcels) to control the area and maximize the future use of the land. Because the purchase agreement stipulated the client would assume all environmental liability, additional assessment was recommended. Additional work that was conducted included a risk evaluation of the ongoing/future environmental monitoring costs, budgets for additional remediation costs as well as costs to conduct additional Phase II (sampling) investigations.

Industrial Hygiene - Mining Operation
Sespe prepared a comprehensive workplace hazard exposure assessment program for a large active mining facility in Ventura County. The exposure assessment program determines the appropriate occupational exposure limits, presents methodologies for exposure monitoring, prioritizes similar exposure groups for monitoring of each hazard, and dictates the frequency with which exposure monitoring shall be conducted. The program addressed exposure to dust, noise, welding fumes, fuel, heat, and ergonomic hazards. In addition to preparation of the overarching exposure assessment plan, Sespe assists in conducting the exposure monitoring events and interpreting the results.

Industrial Hygiene - Manufacturing Facility
Sespe conducts workplace hazard exposure assessment of many of the industrial process at a large manufacturing facility in southern California. In addition to the sampling, Sespe interprets the results and provides written recommendations on how to proceed. Sampling is commonly conducted to assess employee exposure to dust, solvents, acids, and noise. Sampling is conducted periodically to confirm that exposures are below applicable occupational exposure limits (OEL) and when process or facility changes may impact employee exposure.

Employee Training
Sespe’s senior level, experienced staff conducts many forms of reoccurring environmental and safety training for a facility in Los Angeles. Training services provided include:
- Hazwoper
- Hazard Communication
