In January 2023 we published a recycled Aqua Talk article about upcoming drinking water regulatory changes that were expected in the 2000s. The article was recycled from our December 2000 newsletter. Back then the newsletter was called Tapping In. In February 2023 we again published a recycled Aqua Talk article about upcoming drinking water regulatory changes. This time the article was the October 2008 Aqua Talk article entitled “New Rules in Challenging Times” about our then-recent adoption of the Long-Term 2 Enhanced Surface Water Treatment Rule, Stage 2 Disinfectants/Disinfection By-Products Rule, and the Groundwater Rule. These rules were significant and together applied to all the public water systems in Colorado. In both the early and late 2000s the challenges faced in the U.S. were largely economic, and there were also security concerns.
As we move forward in the 2020s, we again face tremendous challenges in our country and the water industry. The challenges are too numerous to fully elaborate, but many stem from the COVID-19 pandemic and related economic upheaval, including serious supply chain issues. We are also faced with more severe security threats than ever before. Colorado water utilities have been targeted with ransomware attacks and other physical security incidents have occurred as well.
On top of all this, as noted in the lead-in paragraph of the January 2023 recycled article, the 2020s promise to be a decade of substantial changes to the federal Safe Drinking Water Act. I believe that these will be the most significant and intense set of new and updated drinking water rules we have experienced since the early 2000s. In the early 2000s Colorado was well-positioned for a number of these rules because of the way we approached drinking water regulations over a long period of time, such as our disinfection and certain surface water treatment practices, combined with intense planning to get ahead of, or at least early starts on, the arsenic rule, radionuclides rule and groundwater rule. Now, in 2023, I believe that we are once again well-positioned to tackle a number of the challenges associated with the upcoming rules. We have instituted special projects since the late-2010s that will help us with preparations for the Lead and Copper Rule Revisions (LCRR) via the Lead Outreach and Verification Effort (LOVE) project, surface water treatment via the Disinfection Outreach and Verification Effort (DOVE) project, and extensive PFAS sampling. We also have a considerable influx of federal funding dollars via the Bipartisan Infrastructure Law (BIL) to help with the investments that water utilities will need to make in this decade. Additionally, we recently completed the development of a Direct Potable Reuse (DPR) Rule that will support Colorado’s water supply future. The table below summarizes all these new (DPR and LCRR are either completed or underway) and new rules in the 2020s. As of this writing, the EPA’s draft PFAS rule has not been published. The modest change to the Backflow Prevention and Cross Connection Control (BPCCC) Rule slated for August 2023 is not shown.
Please note that states typically have two years, from the date of a final federal rule to adopt and implement it, with compliance dates usually starting soon thereafter. So, for the PFAS rules, states would have until Fall 2025 to adopt the rule. However, some rules have had “early implementation” requirements in the past. Each rule is unique.
As you can see, this is quite a list. While utilities must comply with these rules, states must be able to adopt and adequately enforce the rules to maintain primary enforcement authority or “primacy”. To gain primacy for each rule, detailed “primacy packages” need to be prepared by the state and reviewed by EPA to gain approval. In talking with many of my colleagues across the U.S., many states have experienced such a degree of staff turnover in the last several years, that a number of states have no staff that have previously prepared a primacy package for EPA. But rest assured in Colorado, we still have many experienced staff that have conducted stakeholder engagement processes and prepared primacy packages. As always, we will be engaging stakeholders in developing these rules, a process well underway for LCRR, and also importantly identifying assistance, policy and training needs during those processes as well.
We will strive to help water systems meet these rules and requirements as best as our funding and resources enable us to. But I urge you to learn about these new rules as soon as you can, so that you can best prepare your water system for the challenges that it may face in addressing them and keeping tap water safe for your customers. Thank you.
