SUBJECT: Compliance Evaluation Inspection
City of Lexington
Conjunctive Use Wastewater Surface Irrigation
Permit No. WQ0016165
Davidson County
Dear Ms. Comer:
On December 14, 2015 staff of the North Carolina Division of Water Resources (DWR) Winston-
Salem Regional Office performed a compliance inspection of the subject facility. This inspection
was performed by DWR representative Jim Gonsiewski. The compliance inspection report for this
inspection is enclosed for your review. A separate DWR office file review of self-monit9ring data for
the period of October 2012 through October 2015 was also conducted.
While the majority of the inspection reflects compliance with Permit WQ0016165, the following
items were noted in which permit conditions were not met:
1. Permit Condition IV.4 (Attachment A)limits the effluent into the spray irrigation system to
a monthly average of 9,000 gpd. The review of the Non-Discharge Application Reports
(NDAR) indicate that the monthly average of permitted effluent flow was exceeded in a
number of months during the review period. It is our understanding that an operator is on
site during the entire spray event to ensure no problems (such as ponding or runoff) occur.
This office recommends that the flow rates and spraying events continue to be closely
monitored to prevent permit non-compliance. Additionally, this office would like to
observe an irrigation event at a convenient time for your facility. This office also
recommends that consideration be given to a modification of the current permit to allow for
a higher average daily irrigation rate. This modification can also be completed during the
renewal process for the permit.
2. Permit Condition IV.4 (Attachment A)requires that the effluent be analyzed for total nitrate
three times a years. The facility has been reporting combined Nitrate and Nitrite. Please
report total nitrate on future Non-Discharge Monitoring Reports (NDMR).

Dear Mr. Spach:
Enclosed please find copies of the Compliance Evaluation Inspections form from the inspections conducted
on January 8,2008. The Compliance Evaluation Inspection was conducted by Derek Denard of the
Winston-Salem Regional Office. Present for the inspection was Roger Spach,Water Resources
Superintendent. The facilities were found to be in Compliance with permits WQ0023213,WQ0001318 and
WQ0016765.
Lexington Golf Course-Reclaimed Water Utilization System,Permit No. W00023213
Review of self-monitoring for the period of December 2006 to October 2007 found the following:
• Flow was not recorded on NDMR's for August, September and October 2007. If no flow occurred
this should be indicated on the monitoring report. It was understood from the inspection that at
times the system may be running,but no effluent is being used or stored as reclaimed water. A
biological wastewater treatment system has to be maintained. Therefore effluent is returned to the
collection system during these times.
• The tri-annual parameters pH,TDS,TOC,Nitrate and Chloride were not taken in July 2007 as
required by permit Condition III. 3. This data was made available at the inspection. The July 2007
NDMR should be amended.
• The monthly parameter TSS was not taken in March 2007. This data was made available at the
inspection. The March 2007 NDMR should be amended.
• Fecal Coliform results for 4/12/07 was 25 /100mL. This treated wastewater was not irrigated and
was returned to the system.
• Turbidity was not recorded from April 2007 to October 2007. It was discussed during the
' inspection that turbidity should be recorded on the NDMR as<8 NTU. If effluent exceeds this
value the system is programmed to turn off effluent flow to storage and return upset water to the
collection system.
• Storage freeboard should be recorded on NDAR's according to permit Condition III. 5.
Additionally,Condition II.10 requires a freeboard of no less than 2 feet. Upon discussion during
the inspection it was determined that freeboard should not be an issue for this facility since it is not
the primary treatment system for the City of Lexington. If in the event that there was no freeboard
in the storage tank,the effluent would be returned to the collection system. It,Carolina

• Zones 5 and 7 exceeded hourly application rates on numerous occasions. In addition, one 12-month
floating total was exceeded in October 2007 at 12.79 inches for zone 5. Instantaneous Loading
Rate(in/hr)should be modified for Zones 2, 5 and 7. Annual Loading Rates(in/yr) should be
modified for Zones 1 and 5.
Lexington City-Pilot Spray Irigation,Permit No. W00016165
Review of self-monitoring for the Pilot Spray Irrigation permit WQ0016165 for the period January 2007 to
November 2007 found the following:
• Total Phosphorous was not reported for January,February,March and April 2007. However,
March 2007 was amended for Total Phosphorous. January,February and April 2007 should be
amended as well. It was noted during the inspection that data was available for Total Phosphorous
for every month because it is a requirement for the NPDES permit NC0055786.
The permit describes a facility permitted for 9,000 GPD. However,the NPDES permit is for 6,500,000
GPD. The perinittee reports the same effluent flow on the DMRs(NPDES) and the NDMRs regardless of
how much effluent is actually irrigated. The NDMR has GPD labeled at the top of the column,but is
reported in millions of gallons per day(MGD). Reporting the total flow treated by the system could be
misinterpreted as a violation of the permitted flow. However,the actual flow applicable for spray irrigation
is recorded on the NDAR. In this case, individual daily flows recorded far exceed 9,000 GPD, but the
average daily flow over the month usually does not exceed 9,000 GPD. More importantly irrigation flow
does not result in exceedance of maximum hourly loading(instantaneous)rate of 0.30 inches per hour or
the cumulative loading of 30.0 inches over any twelve month period as outlined in Condition 11.7. The
9,000 GPD flow should not be used as a benchmark for compliance because the system effluent flow is
actually much more.
Please refer to the enclosed inspection reports for additional observations and comments. If you or your
staff have any questions,please call Derek Denard at 336-771-5286.

Permit:WQ0016165 Owner-Facility: City of Lexington
Inspection Date: 01/08/2008 Inspection Type:Compliance Evaluation Reason for Visit:Routine
Inspection Summary:
PERMIT
Non-discharge Permit No.WQ0016165 is for the operation of a 9,000-GPD conjunctive-use spray irrigation system
consisting of 176,000-square-foot spray irrigation area, forty sprinkler heads with a maximum 57-foot cast, and all
associated piping,valves, and appurtenances to serve the City of Lexington,with no discharge of wastes to the surface
waters.
The permit describes a facility permitted for 9,000 GPD. However,the NPDES permit is for 6,500,000 GPD. The
permittee reports the same effluent flow on the DMRs (NPDES) and the NDMRs regardless of how much effluent is
actually irrigated. The NDMR has GPD labeled at the top of the column, but is reported in millions of gallons per day
(MGD). Reporting the total flow treated by the system could be misinterpreted as a violation of the permitted flow.
However, the actual flow applicable for spray irrigation is recorded on the NDAR. In this case, individual daily flows
recorded far exceed 9,000 GPD, but the average daily flow over the month usually does not exceed 9,000 GPD. More
importantly irrigation flow does not result in exceedance of maximum hourly loading (instantaneous) rate of 0.30 inches
per hour or the cumulative loading of 30.0 inches over any twelve month period as outlined in Condition 11.7. The 9,000
GPD flow should not be used as a benchmark for compliance because the system effluent flow is actually much more.
RECORD KEEPING AND SELF-MONITORING
-Self-monitoring was reviewed for the period January 2007 to November 2007.
-Total Phosphorous was not reported for January, February, March and April 2007. However, March 2007 was amended
for Total Phosphorous. January, February and April 2007 should be amended as well. It was noted during the inspection
that data was available for Total Phosphorous for every month because it is a requirement for the NPDES permit
NC0055786.
-Last soil report was done on 11/01/07 by A&L Eastern Agricultural Laboratories, Inc.

USING LEXINGTON'S WASTEWATER
COMPOST
WASTEWATER COMPOST
Lexington' s compost uses material removed from wastewater
during treatment. This material has undergone a preliminary step
to significantly reduce pathogens prior to composting. The City
has a comprehensive pretreatment program in place to keep
objectionable or toxic materials from reaching the treatment
plant.
This material is blended with a bulking agent (bark, wood
chips, leaves, sawdust, etc. ) before composting begins . This
mixture is mixed and aerated for 14 to 30 days. During this time
the materials are stabilized organically. Bacteria produce
temperatures in excess of 130 degrees fahrenheit. This heat
pasteurizes the compost producing a material which is essentially
odorless and free of harmful pathogens .
GENERAL USES
Accepted uses for wastewater compost are as follows :
- Topsoil substitute for land reclamation
- Nursery production of trees and ornamental plants
- Revegetation of disturbed land
- Landscaping around parks and buildings
- In potting mixes
- As a mulch
- Establishing turf grass

•
Precautions : Wastewater Treatment Compost is hygienically and
environmentally safe if it is used properly, but it can become a
hazard and a nuisance if not managed properly. Do not leave in
piles that can become a play area for children.
Acid loving plants : Our staff report that this material be
used around plants such as azaleas only under certain conditions.
Hydrangeas : Our customers report that their plants, which
produced blue flowers, produced pink flowers after compost was put
into or on the soil around the plant.
Lime: It is recommended that soils where compost is applied
be limed to maintain a soil pH of at least 6 . 5 . For most local
lawns, 30 lbs . of agricultural lime per 1, 000 square feet should be
sufficient. For flower beds or other border plantings where
compost is applied at levels approaching those used for mulches, in
excess of 45 lbs. per 1, 000 square feet may be required. Do Not
apply lime where acid loving plants are used.
You may not need to add as much lime as indicated above. For
best results, have the soil tested by the N.C. Department of
Agriculture before applying compost or other materials.
When compost is applied over large areas (as lawns) it can
contribute to water pollution if it is applied at rates greatly
exceeding agronomic rates. For example, do not apply more than one
ton of compost per 1, 000 square feet where fescue grass planted.
(One yard of compost weighs approximately 1, 000 pounds. )

• '
Exceptional Quality Certification
I . Lexington Compost is certified to have metals
concentrations lower than those listed as "High Quality
Concentration Limits" in 40 CFR part 503 . These limits are listed
below:
Metal mg/kg Metal mg/kg
Cd 39 Zn 2, 800
Cr 1, 200 Cu 1, 500
As 41 Ni 420
Pb 300 Mo 18
Hg 17 Se 36
II . Lexington Compost is also certified to meet the "Class A"
pathogen reduction and vector attraction requirements of 40 CFR
part 503 .
III . The two certifications listed above qualify Lexington
Compost as a material of exceptional quality under EPA definitions.
Do not use in gardens where root or leaf crops are grown; in
playgrounds: on frozen, snowcovered, or flooded land; or within 10
feet of surface water. Keep out of reach of children.
For further information on uses, call the Water Resources
Superintendent at 243-2489 or write to:

To: Tom Cadwallader,Permits and Compliance Unit, Groundwater Section, Central
Office, Raleigh
Through: Sherri Knight, Supervisor, Groundwater Section, Winston Salem Regional Office
Cr&
From: Christopher Greene, L.S.S.,Hydrogeological Technician, GW Section, WSRO
Subject: City of Lexington, Spray irrigation,permit renewal#GW 03133/WQ 0016165
On December 4, 2003, C. Greene and Steve Mauney, WSRO WQ Section, and Tom
Cadwallader, Central Office GW Section, met with Mr. Roger Spach, Water Resources
Supertintendent, City of Lexington,to inspect the subject project.
Prior to its inception, WSRO GW Section performed a detailed inspection of this facility,
and was-deemed suitable in terms of design and site characteristics,with existing vegetative
growth, primarily in the form of softwood(pine)trees and subordinate brush, and very deep soils.
The site has undergone something of a transformation;the area is robust in growth,
perhaps in need of some grooming of the understory, as it is relatively thick. The spray heads
appeared to be in good condition; vegetative growth in proximity to the spray heads (see photos)
could use some thinning. Central Office's notes of the overall condition as"not very fancy" is
perhaps an understatement.
This water resource has had a beneficial effect to an area that has been subject to
droughty conditions for an extended period(>5 years). It is recommended that the permit be
reissued,with periodic attention to groundskeeping to improve access to the spray heads.

Commenced at WRD office @ 10am Carolina Ave &Talbert Blvd [phone]
Major items of discussion were as follows:
• The application package does not address the quality of wastewater to be used for
irrigation - Roger explained that they are proposing to build a 'scalping' packaged WWTP
at the golf course and it will pull off raw wastewater from the main interceptor, treat the
flow to reuse standards (no extra nutrient reduction envisioned), spray on the golf course
and or redirect the flow/excess biosolids back into the interceptor and essentially shut the
plant down during the winter months when the NPDES discharge allowances are greater.
Before the new WWTP comes on line and during the winter shut-down, the City will
continue to use City public water supply to irrigate the golf course.Backflow preventers
will be installed to protect against cross connections between the reuse and potable
water supplies.
• [A concern exists on my part, although not discussed at the meeting, in that why are we
permitting a waste disposal system,when there is no waste involved? Until the WWTP
plant is built, they will be irrigating only fresh potable water, as they have done for more
than 50 years. And who knows, it may be another 50 years before they build the
WWTP?]
• NCDENR's CG&L was investigated as a source of funding, but the City was told that their
water and sewer fees are to low to effect repayment of the loans.(and the politics was not
right to up fees just to get the loan) Financing is coming in part from 'credits'for not
having to develop new City water supply and meet the 'mass'limits for NPDES waste
disposal facilities. Their estimates to date are based on an 88 acre golf course and
180,000 gpd of flow. I noted that the actual area of the irrigation system/golf holes is
about 65 acres and the adf will most likely be around 100,000 gpd (the slope of the
terrain is quite steep) Roger will check with the designer to see if they are planning to
irrigate some of the natural, non-golf, areas of the property to make up the area and flow
volumes.
• we discussed the design considerations of underground utilities as conduits of
groundwater flow(are none), perched areas and the need to maintain vertical separation
(normally self controlling on a golf course because golfers don't like wet shoes), use of fill
to change slope and drainage characteristics (mostly for the better from a gw standpoint),
location of existing supply wells (none),wetlands (have been marked and isolated from
development)and seasonal restricted areas (Zone 3?), CEPA status (noted that EA not
required, Roger to check on the FONSI).
• Plans do not address the demolition aspects of what is in the ground now. Roger
explained that the course started in the 1930's with a galvanized pipe water system that
was rehabed to PVC in the late 70's. Some of the piping has been scavanged for the new
system but most will be abandoned in-place. The old pump station has been removed.
• The maximum water the course used in the past was about 40 mg/yr which involved
several major line leaks. The proposed flow for the reuse system is about 66 mg/yr.
• It was noted that monitoring wells will not be required as part of the permit because it is
proposed as a 'golf course reuse system'. The owner may continue to use the onsite
monitoring wells that were installed by S&ME as part of the data collection necessary for
the irrigation system design.
Observations at the golf course were as follows:
Old asphalt cart paths were pulled up and deposited in a low area nw of water tower and
on a parking area near the CCBlvd and CC Road intersection.
Several holes were entirely regraded, silt fencing extensive, course closed for rehabing

till next summer?, contractor on site for the course work, picture taken, cold/damp, hard to get a
flat lie even on the fairways, not much surface water(no ponds, flowing water), short course (5-6k
yds?)
GW flow in multiple directions based on topo divides. Few recharge areas, mostly
discharge.
Observations at the WWTP spray area:
Tree stands in the recharge area — 15'to 20', quite dense and filled with undergrowth.
PVC spray system not very fancy, trenches not backfilled, nor deep. metal stakes
installed to keep spray heads upright. in place for about 4 years and definitely providing moisture
to a drought stricken area. City plans to develope an additional several hundred acres fo rthe
same application. WWTP doing a $3m(?) nutrient removal expansion. Recently had an upset of
solids into the effluent holding pond which resulted in a fine. several pictures taken.

was rehabed to PVC in the late 70's. Some of the piping has been scavanged for the new
system but most will be abandoned in-place. The old pump station has been removed.
• The maximum water the course used in the past was about 40 mg/yr which involved
several major line leaks. The proposed flow for the reuse system is about 66 mg/yr.
• It was noted that monitoring wells will not be required as part of the permit because it is
proposed as a 'golf course reuse system'. The owner may continue to use the onsite
monitoring wells that were installed by S&ME as part of the data collection necessary for
the irrigation system design.
Observations at the golf course were as follows:
Old asphalt cart paths were pulled up and deposited in a low area nw of water tower and
on a parking area near the CCBlvd and CC Road intersection.
Several holes were entirely regraded, silt fencing extensive, course closed for rehabing

till next summer?, contractor on site for the course work, picture taken,cold/damp, hard to get a
flat he even on the fairways, not much surface water(no ponds,flowing water), short course(5-6k
yds?)
GW flow in multiple directions based on topo divides. Few recharge areas, mostly
discharge.
Observations at the WWTP spray area:
Tree stands in the recharge area - 15'to 20', quite dense and filled with undergrowth.
PVC spray system not very fancy,trenches not backfilled, nor deep. metal stakes
installed to keep spray heads upright. in place for about 4 years and definitely providing moisture
to a drought stricken area. City plans to develope an additional several hundred acres fo rthe
same application. WWTP doing a $3m(?)nutrient removal expansion. Recently had an upset of
solids into the effluent holding pond which resulted in a fine. several pictures taken.

Nathaniel Thornburg, WGS—CO Reviewer
This application is for the renewal of a spray irrigation permit (<10,000 gpd) on a dedicated field (-4
acres)at the existing Lexington's regional wastewater treatment plant on Glendale Road. The field was
originally cleared of natural trees and has repopulated with volunteer pines as a pilot spray project.
Irrigation water is obtained from the plant's effluent and is sprayed through a solid set fixed nozzle
system.
An inspection of the field in November 2003 showed a considerable amount and variety of growth in
spite of the recent four years of natural drought in the area. The pilot project appeared successful in
producing a vigorous undergrowth and tree stand of pines.Because there is no groundwater monitoring
wells surrounding the site, there is no basis for estimating the impact of the system on the surficial
aquifer. The field is located on a naturally high bluff area, which appears to have adequate (>3 feet)
vertical separation between the high water table and the land surface. We are including the vertical
separation clause in the new permit to bring it current with other similar permits now being renewed.
The Groundwater Section has reviewed the subject renewal permit application and recommends re-
issuance of the permit with the following conditions:
1. Vertical Separation Requirements:
Industrial waste shall not be applied or discharged onto or below the land surface when the
vertical separation between the waste and the seasonal high water table is less than three(3)feet,
unless the permittee has demonstrated to the Director or his delegate, by using predictive
GW03133.doc Page 1 of 2 Rev. 12-03

calculations or modeling methods acceptable to the Director or his delegate,that such placement
will not result in the contravention of classified groundwater standards.
2. Applicable Boundaries:
a. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A
NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary for the
disposal system individually permitted on or after December 30, 1983 is established at either 250
feet from the waste disposal area,or 50 feet within the property boundary,whichever is closest to
the waste disposal area. An exceedance of Groundwater Quality Standards at or beyond the
Compliance Boundary is subject to remediation action according to 15A NCAC 2L.0106(d)(2).
b. The REVIEW BOUNDARY is established around the disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area.Any exceedance of standards
at the Review Boundary shall require action in accordance with 15A NCAC 2L .0106(d)(1).
3. Additional Requirements:
Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
If there are any questions please call Tom Cadwallader at 715-6173.

Re: City of Lexington
Permit#WQ0016165
Conjunctive Use Spray Irrigation System
Davidson County
Subject: Miscalculation of 12 Month Running Totals of Inches Applied
Dear Mr. Mauney:
This is to confirm substance of our previous conversation regarding the above matter.
In a routine review of DMR's submitted for Lexington's Spray Irrigation System (WQ0016165) I
have found an error in the way that the 12 month total of effluent was applied. A review of past
DMR's showed that an error was made in the formula used to calculate 12 month totals of
wastewater applied. This error was first made in April 2001 and was included in all DMR's which
followed. The error resulted in the limit for 12 month totals being exceeded 6 times.
I am attaching a copy of a spreadsheet which shows the problem. There are four columns of figures
going from left to right, the columns are for 1) month/year; 2) inches applied; 3) 12 month total
inches applied (corrected); 4) 12 month total inches applied (reported).
Please forward questions regarding this matter to my attention at 336-248-3970.
Sincerely,
Roge Spach
