Revised Total Coliform Rule:

Sample Site Form

Why do I need to develop a Revised Total Coliform Rule Sample Site Plan?

The Revised Total Coliform Rule Sample Site Plan is a written plan that identifies sample sites for routine coliform monitoring. The plan must be reviewed and approved by DEQ to ensure it meets all requirements. All Non-Community and Non-Transient Non-Community Public Water Supplies must submit an initial Revised Total Coliform Rule Sample Site Form to DEQ by March 31, 2016.

The Revised Total Coliform Rule Sample Site Form includes the following items that must be completed:

1.  Standard operating procedure (SOP) for Revised Total Coliform Rule monitoring

2.  List of routine sample sites

3.  For water systems serving groundwater, locations for triggered monitoring

4.  Revised Total Coliform Rule water system map

First review the Revised Total Coliform Rule Sample Site Plan General Requirements, and then complete the Revised Total Coliform Rule Sample Site Template on the following pages and submit it to DEQ by March 31, 2016. If you have any questions, please contact PWS Compliance at (405) 702-8100.

A.  Revised Total Coliform Rule Sample Site Plan General Requirements

1.  Standard operating procedure (SOP) for Revised Total Coliform Rule monitoring

Your water system’s SOP for Revised Total Coliform Rule monitoring will prescribe how monitoring is conducted. Complete your water system’s SOP in Part 1. Revised Total Coliform Rule Monitoring SOP of the template. The SOP should include:

·  Number of routine samples required each month or quarter.

·  Description of how all areas of the water system are represented by routine sample sites.

·  Description of how all routine sample sites will be used on a rotating basis to ensure representative sampling.

·  Requirement for three repeat samples following a total coliform positive routine sample.

·  Criteria for choosing repeat sample sites.

·  Dates of operation, for seasonal systems.

·  Description of how triggered monitoring of groundwater sources will be conducted, for water systems serving groundwater.

2.  List of routine sample sites

Your routine sample sites should be selected carefully so that you obtain representative samples of your entire water system. Choose as many routine sample sites as you need to represent the entire water distribution system. Add routine sample sites in Part 2. Revised Total Coliform Rule Routine Sample Sites of the template. Considerations include:

·  Routine sample sites may be a water tap or dedicated sampling station.

·  Routine sample sites must be listed with a description of the sample tap.

·  Routine sample site codes will take the form of TC001, TC002, TC003, etc.

·  Suitable repeat sample sites within 5 water taps upstream (closer to the well) and downstream (farther away from the well) of each routine sample site must be available. However, repeat sample sites should not be listed because you may use any suitable sample site within 5 water taps for repeat monitoring.

·  All areas of your water system, including the far end of the water system and areas using water from different sources, should be represented in the routine sample sites to ensure representative sampling. At least three routine sample sites are recommended.

·  Sample sites with the following types of faucets are NOT recommended:

o  Ball-joint faucets with a single valve for hot and cold water

o  Swivel faucets that swing back and forth

o  Outdoor faucets

o  Faucets with leaky packing material around the stem

o  Faucets with an under-the-sink treatment device, such as a water softener or filter

o  Faucets that face upward or sideways

o  Frost-free hydrants

o  Faucets with threads on the inside of the spout

o  Faucets at janitorial, commercial, or kitchen sinks where bacteriological contamination is likely

3.  For water systems serving groundwater, locations for triggered monitoring

If your water system serves groundwater, you must submit a list of all groundwater triggered monitoring locations for all wells subject to triggered monitoring under the Ground Water Rule. Add triggered sample sites in Part 3. GWR Triggered Monitoring Sample Sites of the template.

4.  Revised Total Coliform Rule Water System Map

Your Revised Total Coliform Rule Water System Map should show the entire area of your water system. Requirements for the water system map include:

·  Your Revised Total Coliform Rule Water System Map should be submitted on an 8.5 x 11 sheet of paper.

·  All routine sample sites must be shown on the map. (Again, keep in mind that suitable repeat sample sites must be available within 5 water taps upstream and downstream from each routine sample site.)

·  All water system facilities, such as chlorination stations, water tanks, pressure tanks, and water treatement plants must be shown on the map.

·  All water sources, such as wells, surface water intakes, and connections to other public water supplies.

·  For each well, show the location of the raw water sample tap.

Mapping websites can provide an aerial view of your water system to assist with creating your map:

o  Google Maps at www.google.com/maps

o  DEQ’s Flex Viewer at www.deq.state.ok.us/mainlinks/gis/index.html

Hand-drawn maps are acceptable as long as they are legible and an accurate representation of the water system.
