Matt and Doug,
I have reviewed the plans for the Pleasant Ck Campground improvements project (System 09014) and I have the
following comments:
1) Both the tle block of the drawings and the tle/header on the specificaons say “GAOA Fishlake Campground
Water System…” is this correct. I understand this is the Fishlake Naonal Forest but this project is for the Pleasant
Creek CG Water System.

2) There is a Surge/Pressure Tank called out (Note 10, Sheet D5). Is this supposed to hold or sustain pressure or is it
only a surge tank? If it is to hold pressure, then we add it to our inventory as a facility (likely HD001, Oak Ck Pressure
Tank). In this case, the underground vault it is housed in has to have proper drainage (see rule below) to ensure it
won’t flood. How will this be accomplished since I don’t see a drain to daylight in the vault. A gravel sump is also
allowable if the site is not subject to flooding.

This same drainage requirement below applies to the underground PRV installaon shown on Sheet D6.

2) Flood Protecon and Site Drainage.
(a) A pump staon shall be located at, or protected from, flooding to an elevaon of at least three feet above
either the 100-year flood or highest recorded flood, whichever is higher.
(b) The site for a pump staon shall be graded to direct surface water drainage away from the pump staon.
(3) Pump Staon Drainage and Flooding Prohibion. A pump staon:
(a) may not be subject to flooding;
(b) shall be drained to prevent water from collecng on the floor; and
1) (c) shall provide an outlet for drainage from pump glands, air release valves, and other equipment
without allowing water to flow across the floor to reach the outlet. See Subsecon R309-550-6(6) for
clearance requirements for air release vent pipes discharging to floor drains

3) Are these tanks prefabricated or is the tank manufacturer to determine the tank dimension? There are no details toshow the height, width, length, distance between access openings (two each tank), where the air vent is to belocated, etc. on each tank. Since these two tanks will be different sizes (2000 and 4000 gallons), how will themanufacturer know how these are to be constructed?
4) The air vent on the top of the tank appears to vent the supply line as well as the tank, is that correct? Normally, theair vent on the tank is for the tank only, so I want to be sure that the air vent detail applies to the tank air vent.
5) Can you describe what a “Double Outlet Vent” is (Screened Vent Detail on Sheet D6)? I just need to know that thismeets the DDW rule for a downturned air vent. (Just a side note that mushroom style vents might not be allowed in
future rules, since you can’t readily verify if the screen is sll in good shape. It might be beer to go with more of a
downturned candy-cane style to avoid future modificaons).
6) Sheets W14 and W15 describe the Chlorinator box as being disposed of. It is my understanding that the chlorinator
will remain as it is currently listed as Acve in our inventory. Where will the chlorinator be installed if the exisng box
will be removed?
