Because of increasingly stringent regulations, hazardous waste management facilities need closure and post-closure plans. The technical expertise of Soil Pacific Inc. (SPI) encompasses the following aspects of closure and post-closure activities:
- Closure plans that conform to RCRA requirements
- Site characterization investigations to assess the extent of existing contamination
- Retrofitting or demolition of existing facilities
- Collection and disposal of material from surface impoundments or tanks
- Collection and treatment of landfill leachate and liquids from surface impoundments or tanks
- Transport of contaminated materials
- Gas collection and treatment
- Ground water control and cleanup
- Surface water control and cleanup
- Capping design
- Development of final grades
- Construction oversight
- Final-use plans
- Long-term monitoring plans
- Cost estimates
SPI personnel can produce a conceptual plan to submit when applying for a RCRA permit. They also have the expertise to prepare detailed drawings and specifications when it is time for final closure, develop cost estimates, and compare the costs of design alternatives to ensure that the most cost-effective design is implemented. SPI personnel are familiar with the stringent regulations that are applicable to closure and post-closure plans, including the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments of 1984. These regulations include:
- Minimal technical standards for future hazardous waste surface impoundments;
- Retrofitting, or closure with 30 years of post-closure care, or the clean closure of existing hazardous waste surface impoundments
- Land disposal restrictions to be placed on one-third of all listed hazardous waste.
SPI personnel are experienced in working with regulatory agencies to develop plans and designs to meet regulatory requirements.
During implementation of the closure plan, SPI can provide construction management services, such as provision of on-site inspection and review of shop drawings, preparation of operation and maintenance manuals to simplify the upkeep of the closed facility, development of monitoring plans, and assistance in the on-site monitoring and sampling.
When closure and post-closure plans are developed, the client can be assured of receiving a cost-effective design that meets their needs as well as the regulatory requirements.
