vvEPA _ United States Environmental Protectior Agency Revised Total Coliform Rule (RTCR) Placards The U.S. Environmental Protection Agency (EPA) developed a collection of six e-fillable placards on the requirements of the Revised Total Coliform Rule (RTCR). Primacy agencies should use these placards to conduct training and outreach to small public water systems (PWSs) serving 1,000 or fewer persons. For non-seasonal PWSs, there are three placards: 1. Serving 1,000 or Fewer People that Collect Routine Total Coliform 2. Serving 1,000 or Fewer People that Collect Routine Total Coliform 3. Serving 1,000 or Fewer People that Collect Routine Total Coliform For seasonal PWSs, there are two placards: 4. Serving 1,000 or Fewer People that Collect Routine Total Coliform 5. Serving 1,000 or Fewer People that Collect Routine Total Coliform For aii PWS, there is one placard: 6. Serving 1,000 or Fewer People Requiring a Level 1 or Level 2 Asse The placards are published as a fillable form in Adobe PDF The placards are e-fillable in Adobe Acrobat or Adobe Reader*. Each form is designed with a different publication number to allow for unbundling the collection while maintaining the metadata. *Note: some of the following steps may not function in Adobe Reader (e.g., deleting pages). • E-fillable Fields — Information entered in any of the following fields, is replicated to the same fields in the other placards within the collection; o Lab Contact o State Contact o State Website • E-fillable Fields - Information entered in any of the following fields, does not replicate: o Site location (ex. address, location description, etc.) o Site location (alternative address, location description, etc.) - if a second sample location is needed o Expected sample day (in the month, quarter, or year) o Number of TC samples to be collected o Routine and repeat sample locations (non-seasonal placards) Steps to complete the placards Step 1 - To maintain the fields that replicate, complete these fields first (noted above). Step 2 - [Save] the PDF. Step 3 - If you do not want the collection, [Delete] the pages that are not relevant. • View [Page Thumbnails], click on page(s) not relevant to the water system, right click, and click [Delete], Step 4 - Complete the remaining e-fillable fields. Step 5 - [Save] the PDF. Step 6 - [Print] the PDF by page or collection. • [File]/[Print], • Select [Shrink oversized pages], • Uncheck [Print on both sides of paper], • Under [Printer properties] select [11X17 paper (Ledger size)]. If 11X17 is not available select [8 J4X14 (Legal size)]. Note: As the default, these placards are set to font size 13 for printing to 11X17 paper size so they can hang on the wall and remain readable. If they are printed on smaller paper (e.g., 8 ZzXll, 8 >4X14) the format dimensions will shift (i.e., more white space on the top and bottom), but they will be readable.
