Emission Monitoring and Waste Regulations (e.g. Waste Permit) Compliance Services
Landfill services companies are engaged both by commercial landfill/ waste management companies, and local authority waste disposal departments to carry out all monitoring and landfill site maintenance work needed for regulatory compliance of a landfill. These contracts are normally set up as period contracts, and bid for competitively, generally for 2 to 6 year periods.
The monitoring work needed varies from site to site, and the condition of the site (operational, closed but not restored, and closed and restored) with a low permeability cap, may include:
- air pollution monitoring, gas sampling, water testing, air quality testing, noise pollution assessments and methods of noise nuisance abatement, landfill gas sampling, surface water level monitoring, landfill leachate quality analysis
All these tasks are highly specialized and need the skills of trained landfill technicians to carry them out. Owners of landfill sites can do this themselves, but they would need to employ a team of people to bring together sufficient breadth of knowledge to cover all the skills needed.
That’s why Landfill Management Services Companies are becoming increasingly more popular and growing in size. A competent landfill management services company will take on responsibility to carry out all actions necessary to effectively look after old tips (landfills) on behalf of the owner/ operator, and take the necessary actions when necessary to protect the environment, as required by the environmental regulatory authority.
An vital part of Waste Permit compliance for landfills is Landfill Leachate Permit Compliance, and the tasks which a waste permit compliance service can provide are described in the next paragraph. In the later paragraphs of this article, we also identify the work that Landfill Management Services Companies carrry out to ensure compliance with regulatory constraints on landfill emissions to the air and groundwater.
