Today I would like to briefly answer the following questions:
•What are the new Emission Guidelines for existing Municipal Solid Waste Landfills
•What does the DAQ have to do as a result of this Rule?
•Which landfills are effected by this Rule?
•What are the regulated pollutants?
•What are the impacts on the DAQ?
•What are the impacts on the government owned and privately owned landfills?

Emissions Guidelines 40 CFR Part 60, Subpart Cf
The new Emissions Guidelines:
On a recurring basis, the United States Environmental Protection Agency (US EPA) will revise or promulgate new air quality regulations that effect the existing industries in North Carolina and around the United States.
Such new air quality regulations for sources (Emission Guidelines) for the control of greenhouse gases from existing Municipal Solid Waste Landfills was published by the US EPA in the Federal Register on August 29, 2016 under 40 Code of Federal Regulations Part 60, Subpart Cf.

What does North Carolina have to do?
States with EPA approved implementation plans such as North Carolina are required to develop (or revise) their air quality regulations and submit a State Plan to the US EPA for approval.
The current rules for existing municipal solid waste landfills is located in section 15A NCAC 2D .1700. These rules have been revised to reflect the new requirements under 40 CFR Part 60, Subpart Cf.

Affected Landfills
Each existing municipal solid waste landfill that accepted waste since November 8, 1987 and that commenced construction, reconstruction, or modification on or before July 17, 2014.

Affected pollutants
Landfill gas contains non methane organic compounds and methane. Methane is a potent greenhouse gas and accounts for approximately 50% of landfill gas volume. The Emission Guidelines controls these pollutants by the lowering of the emission threshold for when landfills are required to install gas collection and control systems.

Impacts on the Division of Air Quality
•2D .1700 rules will have to be revised to meet the requirements of the Emission Guidelines.
•The DAQ will go through the approval process for Rule revision in the State Implementation Plan.
•The DAQ will revise the 29 permits that will be modified to meet the requirements of the 2D .1700 rules after the EPA has approved the Rules.

Impacts on the private and government owned municipal solid waste landfills
•Twenty-nine existing facilities will have to submit applications to have their permits revised to meet the new State Rules.
•Twenty-three of the existing landfill facilities will have to develop a monitoring plan for the gas treatment system. This is a new requirement under the new Emission Guidelines.
•Five of the existing landfill facilities will have to submit a design plan for their voluntary gas collection and control systems.
•Four government owned landfills will have to install gas collection and control systems because the
threshold was lowered from 50 Mg/year to 34 Mg/year.

The benefits of this Rule will be that landfills will be controlled earlier than currently required thereby reducing future greenhouse gas pollution from the landfills that don’t utilize voluntary collection and control systems.
•Are there questions?
