Cost of Compliance to Rise for Missouri Wastewater Treatment

Recently, the EPA released a decision letter approving most of the changes to the Missouri Department of Natural Resources’ (MDNR) water quality standards. While this will bring the state in closer compliance with the federal Clean Water Act, the new rules mean pollution limitations will be extended to thousands of lakes and tens of thousands of miles of rivers not previously under strict regulation. That will mean higher costs for Missouri’s water treatment utilities.

According to a report issued by MDNR, upgrading the state’s wastewater treatment plants to meet strict federal standards will cost between $430 million on the low end and $1.2 billion on the high end. However, most municipalities did not set high enough utility fees to cover the cost of regular improvement projects when regulation was more lenient. With the cost of needed upgrades now looming, localities will be forced to find more funds, which means wastewater utility rates, or other forms of local taxation, are likely to increase statewide in the near future.

Conforming to higher water quality standards in the most economical manner possible has pushed many municipalities across the nation and in Missouri to privatize their water utilities. Cities usually receive an upfront payment for leasing these systems, and while the private owners often raise rates, the increase is usually less than what the public utilities planned to do absent of privatization.

The city of Arnold in Jefferson County is considering just such a privatization plan partially in response to these types of costs. We have written before how this deal can benefit Arnold financially, and should it succeed, the privatization plan could become a model for other municipalities as they decide how to deal with increasing regulatory burdens for water treatment.
