HB 1632 Mississippi House · 2026 Regular Session

Community Public Wastewater System Infrastructure Sustainability Act; create.

HB 1632 establishes a statewide accountability system for Mississippi's community public wastewater systems (serving at least 15 year-round connections or 25 consumers). It requires the Mississippi Department of Environmental Quality to create a letter grade system (A-F) based on objective criteria including permit compliance, water quality standards, financial health, infrastructure condition, and customer satisfaction. The department must publish annual performance scores and letter grades for each system online, and systems must notify customers of their grade within 30 days. This law directly affects local wastewater providers by mandating transparent public reporting of their service quality and sustainability.

MODERATE
The Senate made several substantive amendments to HB 1632 before sending it to the Governor. The most significant changes expand the definition of covered wastewater systems to include privately owned ones, shift rulemaking authority from the Department of Environmental Quality to the Commission on Environmental Quality, narrow the minimum letter grade criteria from six factors to three, and add a new section clarifying that letter grades will not affect a project's ranking under the Water Pollution Control Revolving Loan Fund Program.
SCOPE

The definition of 'Community Public Wastewater System' now explicitly includes systems that are 'whether publicly or privately owned,' expanding the bill's coverage to private wastewater systems.

A new Section 29 was added stating that the letter grades and scores under this act shall not affect a project's ranking under the department's Water Pollution Control Revolving Loan Fund Program (Section 49-17-85), and that the accountability framework is separate and independent of that program's criteria.

DEFINITION

A new definition for 'Commission' (meaning the Mississippi Commission on Environmental Quality) was added to Section 2, supporting the shift in rulemaking authority.

REQUIREMENT

The minimum criteria for the wastewater system letter grade schedule were reduced from six factors (permit compliance, water quality standards, financial sustainability, O&M performance history, infrastructure condition, and customer satisfaction) to three (permit compliance, O&M performance history, and infrastructure condition). Water quality standards, financial sustainability, and customer satisfaction are no longer listed as minimum criteria.

In Section 22 (drinking water section), the language for point values was narrowed from 'each standard set forth in this section and other assessed criteria as determined by the board' to 'the criteria established in accordance with this section,' removing the board's discretion to add additional assessed criteria beyond those specified.

ENFORCEMENT

Rulemaking authority for the wastewater letter grade schedule was shifted from the Mississippi Department of Environmental Quality ('the department') to the Mississippi Commission on Environmental Quality ('the commission'). The same shift applies to the regulation governing how systems notify customers of their grades.
