Georgia Power continues to make progress towards the closure of seven ash ponds at Plant Yates with the dewatering process scheduled to begin in mid-May. Dewatering marks a significant step towards completing the closure process, and Georgia Power's ash pond closure plan for Plant Yates is specifically designed for the site to help ensure water quality is protected every step of the way.
Four of the ash ponds nearest the river at Plant Yates are to be completely excavated with the ash consolidated with the remaining three ponds, which will be closed in place using advanced engineering methods and technologies. Ash pond closures are site-specific and consider multiple factors, such as pond size, location, geology and amount of material; and each closure is certified by a team of independent, professional engineers.
"As we begin the dewatering process at Plant Yates, we are pleased with the progress we have made on our ash pond closure process throughout the state at all of our plants," said Mark Berry, vice president of Environmental & Natural Resources for Georgia Power. "We continue to focus on safety and meeting all compliance requirements throughout the process to fulfill our longstanding commitment to protect the environment and local communities. We have invested in appropriate water treatment systems to help ensure that our dewatering process is protective of the area's rivers. Throughout the process, clear communication to our customers and the community about our progress remains a priority."
The ash pond dewatering plan for Plant Yates that has been approved by the Georgia Environmental Protection Division (EPD) identifies the enhanced water treatment system, controls and monitoring that will be used during the process to help ensure that the water discharged is protective of water quality standards. The planned onsite closure methods will be permitted and regulated by the EPD.
To date, the company has removed two of the seven ash ponds at Plant Yates, completed engineering and feasibility studies and filed permit applications with the EPD for the remaining ash ponds on site. Communication regarding the closure plan is provided through EPD notifications, advance public notice of permits and updates to local homeowners and local media.
Georgia Power first announced its plans to permanently close all of its ash ponds in September 2015, with initial plans released in June 2016. The company is in the process of completely excavating 19 ash ponds located adjacent to lakes and rivers with the remaining 10 being closed in place using advanced engineering methods and closure technologies.
In November 2018, Georgia Power completed the submission of 29 Coal Combustion Residuals (CCR) permit applications as required by the Georgia CCR rule for ash ponds and landfills. These permit applications outlined significant and detailed engineering information about Georgia Power's ash pond closure plans and landfill operations plans. The permitting application process was developed and completed with significant internal and external resources supported by multiple third-party consulting and engineering firms.
Georgia Power's ash pond closure plans fully comply with the federal CCR rule, as well as the more stringent requirements of Georgia's state CCR rule. Georgia was one of the first states in the country to develop its own rule regulating management and storage of CCR such as coal ash. The state rule, which goes further than the federal rule, regulates all ash ponds and landfills in the state and includes a comprehensive permitting program through which the EPD will approve all actions to ensure ash pond closures are protective of water quality.
In 2016, the company announced that all ash ponds will stop receiving coal ash in three years and the significant construction work necessary to accommodate the dry-handling of ash is on track to be completed in 2019. Today, more than 60 percent of the coal ash Georgia Power produces is recycled for various beneficial uses, such as Portland cement, concrete and cinder blocks.
