All landfills regulated under the NESHAP air program must comply with updated federal regulations by September 2021, including new requirements for landfill gas beneficial use treatment systems and gas system design plans. Additionally, the EPA is finalizing a federal plan implementing new NSPS air rules for landfills modified or constructed before July 2014, and not yet covered under an approved state plan.
At the state level, as part of a continued focus on greenhouse gas (GHG) reduction, Maryland MDE is expected to publish new regulations this year addressing landfill methane control.
Jacob Shepherd, P.E., will cover what landfills need to do to comply with the updated federal regulations and will discuss anticipated new requirements under the MDE regulatory initiative as an example of the direction states are moving.
This discussion takes place at REVISION 2021, an online conference.

This paper, presented at A&WMA’s 111th Annual Conference details the Tier 4 process and the potential issues that have arisen from conducting a Tier 4. This paper also assesses potential Tier 4 sites, exceedance reporting, wind monitoring, additional SEM equipment requirements, penetration monitoring, notification and reporting requirements, and impacts on solid waste landfills that will use the Tier 4 SEM procedure for delaying GCCS requirements. This paper reviews the changes between the draft NSPS and the final version of the new NSPS that was promulgated.
