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  
[23-253-P] 
The Maryland Energy Administration proposes to amend Regulations  .01—.13  under COMAR 14.26.03 Maryland Efficiency 
Standards . 
Statement of Purpose  
The purpose of this action is to implement the Maryland Efficiency Standa rds 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  
I. Summary of Economic Impact.  In FY24 expenditures will increase by $100,000 to initiate compliance procedures within 
the agency.  
II. Types of Economic Impact.

E. On other industries or trade groups:  NONE    
F. Direct and indirect effects on public:  NONE    
III. Assumptions.  (Identified by Impact Letter and Number from Section II.)  
A. Agency expenditures increase for the purposes enforcing compliance.  
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.
