III. EXISTING FACILITIES: MODIFICATION AND RENEWAL APPLICATIONS
1. Are there appropriately certified Operators in Charge (ORCs) for the facility? ❑ Yes ❑ No ® N/A; This permit
does not require ORCs, but the system is contracted with AQWA for service.
ORC: Certificate #: Backup ORC: Certificate #:
2. Are the design, maintenance and operation of the treatment facilities adequate for the type of waste and disposal
system? ® Yes or ❑ No
If no, please explain:
Description of existing facilities: This is a SFR drip system with UV and 1 application field divided into 3 zones.
Proposed flow:
Current permitted flow:
Explain anything observed during the site visit that needs to be addressed by the permit, or that may be important
for the permit writer to know (i.e., equipment condition, function, maintenance, a change in facility ownership,
etc.) The audible/visual alarm for the UV system is not operational. The UV system appears to be operating
correctly. Bulbs are replaced annually by AQWA, with new bulbs installed June 5, 2018. The homeowner also
does a good job of documenting system checks, with minimal missed weekly inspections; however, because the
UV is NOT connected to telemetry the audible/visual alarm system needs to be repaired. The AQWA technician
would have installed the sensor. but did not have the hart on hand.

assimilating the waste? ® Yes or ❑ No

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
As built site map. MRO
files only have proposed
plans dated 5-21-2004.
MRO attempts to geolocate with assigned cell phones and application software
have proven insufficient under tree cover on this site. However, the WSW and
Septic tank gps data acquired appear reasonable and neither of these two items
match the originally proposed plans. WSW is West of the home and septic
tanks are East of the home. (See attached Goo le Earth map).
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
Sensor installation for UV
alarm system
MRO staff is okay with issuance of the permit renewal and cover -letter notice to
repair the referenced UV sensor, as it does not affect treatment, the UV bulbs
were just replaced and the owner does a good job with his weekly inspections.
5. Recommendation: ❑ Hold, pending receipt and review of additional information by regional office
❑ Hold, pending review of draft permit by regional office
® Issue upon receipt of needed additional information
❑ Issue
❑ Deny (Please state reasons: )
6. Signature of report preparer: Maria Schulte
Signature of regional supervisor: I A"•tw H P44
