Subtitle 26 MARYLAND ENERGY ADMINISTRATION

14.26.03 Maryland [Energy] Efficiency Standards

Authority: State Government Article, §9-2006, Annotated Code of Maryland

Notice of Proposed Action

[24-059-P]

The Maryland Energy Administration proposes to amend Regulations .01, .03—.06 and .08—.13, repeal existing Regulation .02, and adopt new Regulation .02 under COMAR 14.26.03 Maryland Efficiency Standards.

Statement of Purpose

The purpose of this action is to implement the Maryland Efficiency Standards Act by establishing minimum efficiency standards for certain new products sold or installed in the State and to establish testing, certification, inspection, and enforcement procedures for ensuring compliance with established standards.

Estimate of Economic Impact

1. Summary of Economic Impact.In FY25 expenditures will increase by $150,000 to initiate compliance procedures within the agency.
2. Types of Economic Impact.

III. Assumptions. (Identified by Impact Letter and Number from Section II.)

1. Agency expenditures increase for the purposes of enforcing compliance and providing access to an appliance efficiency database and for outreach efforts.

Economic Impact on Small Businesses

The proposed action has a meaningful economic impact on small businesses. An analysis of this economic impact follows:

Small businesses will be limited in the supply of certain retail items available from wholesale and for resale. Impacts are mitigated by an allowance for business owners to retain any stock on hand prior to the effective date of the relevant efficiency standards.

Impact on Individuals with Disabilities

The proposed action has no impact on individuals with disabilities.
