Manufactured Gas Plant (MGP) sites are among the most challenging remediation projects due to their complex contamination profiles and regulatory scrutiny. These legacy industrial sites, once used to produce gas from coal or oil, often contain hazardous byproducts such as coal tar, polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). Left untreated, these contaminants can impact soil, groundwater, and even air quality. At O6 Environmental, we help public and private sector clients navigate MGP remediation efficiently and compliantly.
What Affects the Cost of MGP Remediation?
MGP remediation costs can vary significantly depending on several critical factors:
- The size and history of the site, including how many years it was operational.
- The type, concentration, and depth of contaminants present in soil and groundwater.
- Site accessibility and proximity to sensitive receptors like schools or water sources.
- Regulatory oversight level and permitting complexity.
- Remediation technology selected—excavation, thermal treatment, or in-situ stabilization.
- Volume of waste requiring off-site disposal and associated transport logistics.
Typical Remediation Timeline
Remediation projects at MGP sites typically span 12 to 36 months, from site investigation to final closure. The timeline can be influenced by:
- Initial site characterization and sampling campaigns.
- Design and approval of the remediation work plan by regulatory agencies.
- Seasonal construction windows and weather conditions.
- Material handling and waste disposal coordination.
- Post-remediation monitoring and reporting cycles.
