How to Notify Customers of a Noncommunity PWS of a Nonacute Chemical Violation

These instructions apply to you if you own or operate a noncommunity public water system—for example, the water system at a camp, prison, school, or similar facility. To notify customers of a violation of the maximum contaminant level (MCL) for chemicals listed in the rules other than nitrite or nitrate, you must:

1. Notify customers within 30 days of when we notify you of the MCL violation. [Title 30 Texas Administrative Code (30 TAC) Paragraph 290.122(b)(2)]
2. Use the appropriate mandatory language. [30 TAC Subsections 290.122(b)&(d)]
3. Issue the notice in at least one of these ways [30 TAC Subparagraphs 290.122(b)(2)(B)&(C)]:
   • by hand delivery
     –or–
   • by continuously posting the notice in conspicuous places within the area served by the system until we tell you that you may take it down [30 TAC Subparagraph 290.122(b)(3)(B)]
4. Within 10 days of when you issue this notice, submit a copy of the actual notice and the signed Certificate of Delivery of Public Notice to Customers to us via email to PWSPN@tceq.texas.gov, via fax to (512) 239-6050 [30 TAC Subsection 290.122(f)], or via mail to:
