IV. REGIONAL OFFICE RECOMMENDATIONS
1. Do you foresee any problems with issuance/renewal of this permit? Yes or No
If yes, please explain:
2. List any items that you would like the NPDES Unit or Non-Discharge Unit, Central Office to obtain through an
additional information request:
Item Reason
O&M Manual
The O&M manual needs to be updated to reflect the conditions of the new
plant. The O&M plan does not describe maintenance measures for the system
beyond the WWTP. It is important for the permittee to be aware of the need for
regular maintenance schedules for the entire system. Areas beyond the WWTP
(i.e. Azalea Rd, Kiwanis Park) are prone to flooding and to the continuous
scrutiny from the Belvedere community; therefore, the O&M should list
specific measures to be taken in the case of extreme rain events.

3. List specific permit conditions recommended to be removed from the permit when issued:
Condition Reason

4. List specific special conditions or compliance schedules recommended to be included in the permit when issued:
Condition Reason
Application Rates in
Attachment A
It was recommended in a staff report, dated 12/10/2015 that the entire irrigation
area of the golf course as one single disposal zone at a loading rate of 32.2
inches/year. The current permit does not have a maximum loading rate for
these areas. The permit dated 10/3/2007 provided maximum application rates
of 96.7 inches per year on Fairways 1 (consisting of Baymeade, Autryville,
and/or Pactolus soils), 2, 4, 5, 6, 7, 15, 16, 17 & 18 and a rate of 32.2 inches per
year was provided for Fairways 1 (consisting of Foreston and/or Leon soils), 8,
9, 10, 11, 12, 13 and the driving range. The permit issued on 2/9/2015 did not
specify a maximum application rate per field, but in Section III. 14., stated
“Adequate measures shall be taken to prevent reclaimed water ponding in or
runoff from the conjunctive reclaimed water utilization site.”

5. Recommendation: Hold, pending receipt and review of additional information by regional office
