A draft regulatory proposal was first presented on October 16, 2025 pertaining to the installation of ECO nozzles and low permeation hoses at all new and exisiting gasoline dispensing facilities throughout the state of Maryland. In 2016, the Maryland Department of the Environment finalized regulations for the Decommissioning of Stage II Vapor Recovery Systems at gasoline dispensing facilities in Maryland. The installation of ECO nozzles and low permeation hoses adds additional environmental and health benefits to all Marylanders by reducing emissions from these facilities.​ The presentation from the meeting can be found by clicking here​.

Clean Heat Rules - Zero-Emission Heating Equipment Standard (ZEHES) and Clean Heat Standard (CHS)

Stakeholder Meetings on Clean Heat Rules, Fall 2024​ - Winter 2025

In June 2024, Governor Moore issued Executive Order 01.01.2024.19, Leadership by State Government: Implementing Maryland’s Climate Pollution Reduction Plan. The Executive Order requires MDE to propose ZEHES and CHS. MDE’s Climate Change Program is working to adapt a ZEHES Model Rule published by the Northeast States for Coordinated Air Use Management (NESCAUM) and propose a Maryland ZEHES rule in 2025. MDE is also developing a CHS rule with the goal of proposing reporting requirements for covered parties in 2025. ZEHES and CHS together make up the Clean Heat Rules.

Meetings are being held for stakeholders to provide feedback and input on the Clean Heat Rules.
