In Person: Lee Walker Conference Room, Atrium Level, North Tower, Constitution Hall, 525 West

The Department of Environment, Great Lakes and Energy will hold a public hearing to receive public  
comments on proposed changes to the Part 1. Well Construction Code rule set.  
The current rules adopt ASTM International Specification C 150-89 “Standard Specification for Portland  
Cement” (C 150-89) and require the use of Portland Cement that meets the requirements of this  
specification as an approved water supply system component. Up until 2022, the manufacturers of  
Portland Cement made the most common product (Type I) that is compliant with the specification. To  
reduce their carbon footprint, the manufacturers have modified the product and it no longer complies with  
C 150-89. The modified product, which is similar in characteristics, is referred to as Type IL. Modification  
of the language to allow the use of the Type IL would alleviate the need to use less common currently  
approved products and use a more sustainable product that has similar characteristics to Type I for safe  
water supply well construction.  
By authority conferred on by Section 12714 of Part 127, Water Supply and Sewer Systems, of the Public  
Health Code, 1978 PA 368 as amended, MCL 333.12714, gives EGLE rule and construction code  
promulgation authority.  
The proposed rules will take effect immediately after filing with the Secretary of State. The proposed  
issue of the Michigan Register. Copies of these proposed rules may also be obtained by mail or  
electronic mail at the following email address:  
Comments on these proposed rules may be made at the hearing, by mail, or by electronic mail at the  
following addresses until 3/2/2023 at 05:00PM.
