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. Yes, I
agree that this is confusing, but the project naming was an internal Forest Service requirement for the contract
package because the project was a “Great American Outdoors Act (GAOA)” funded project. The project namehad to exactly match the funded project name, which included funds for multiple campground sites across the
Fishlake National Forest. This project is Phase 2 of the larger project.

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? See Sheet D5, General Note 2.2: “THE SURGE TANK AND CHECK VALVE ARE INTENDED TO MAINTAIN
PRESSURE IN THE UPSTREAM LINE FOR PROPER FLOAT VALVE FUNCTION (10 PSI MINIMUM NEEDED AT
FLOAT VALVE).” When the tank inlet float valve closes, there could be opportunity for the supply line pressure
to drop if there is no surge tank. The surge tank is intended to capture a small volume of water when the high
lifter pump shuts down to ensure the supply line holds pressure. This is needed to ensure proper function of
the inlet float valve. 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. The utility box has a 6-inch gravel bottom (see Key Note 7) intended to allow the box to drain if there is
any water in the box. Both utility boxes are not expected to be susceptible to flooding and are expected to drain
well. General Note #2 for the PRV Box on Sheet D6 refers to the detail on D5 for installation, which also shows
the 6” of coarse gravel.

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 to show theheight, width, length, distance between access openings (two each tank), where the air vent is to be located, etc. on each tank. Since these two tanks will be different sizes (2000 and 4000 gallons), how will the manufacturer know how these are to beconstructed? The tanks are typically custom fabricated for each project. Dimensions are left to the manufacturer
based on the tank design and materials used (FRP versus Stainless Steel). Specification 221200-1.3 requiresshop drawings and the dimensions for the items in your question above. See screen capture below. The
available manufacturers that are specified in 221200-2.1 and 2.2 have a history of delivering high qualityproducts for Forest Service projects and typically deliver shop drawings custom to each project that meet or
exceed State standards. These submittals are required to be reviewed by a Forest Service engineer for approvalprior to fabrication.

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, the air vent onthe tank is for the tank only, so I want to be sure that the air vent detail applies to the tank air vent. The tank air vent is
designed to vent both the tank and to act as an air relief for the distribution pipeline when the pipeline is fillingor draining. This is especially critical when the distribution valve at the tank outlet is closed and the line is
draining to prevent suction on the line.
5) Can you describe what a “Double Outlet Vent” is (Screened Vent Detail on Sheet D6)? I just need to know that this meets the
DDW rule for a downturned air vent. (Just a side note that mushroom style vents might not be allowed in future rules, since youcan’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). We typically call for a Morrison Double-Outlet Vent per the screen capture below as an
example. The view is from the bottom of the vent, but the vent features a “double” turned down 90-deg elbow –one elbow on each side. The specifications for this project do not match the detail exactly. Section 21200-2.6calls for a turned down vent with screen – see screen capture below. Either vent should be sufficient to meet
Utah rules, but we can update the drawing detail if needed. Both styles have screens that can be visually
inspected.

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? The
“chlorinator” box shown on W14 and W15 is an older box on the supply line to the Oak Creek tank. The former
chlorinator in this box is no longer in use. This box is no longer needed. Chlorination for the entire system
occurs solely at the existing chlorinator box that is to remain just downstream from the spring source on SheetW2.

Let me know if you have any quesons.

Paul
