Builders FirstSource - Raleigh, LLC currently holds a permit for the above -mentioned wastewater
treatment and irrigation facility (WWTF). The system is sized to treat 3,750 GPD of strictly
domestic wastewater (150 employees at 25 GPD based on a five-day work week) and consists of
the following components:
• One 3,000-gallon septic tank (first -in -series)
• One 2,000-gallon septic tank (second series)
• Two 3,000-gallon pump tanks installed -in -series with two 29-GPM pumps
• Four EZ Treat Model 1200 recirculating media filter pods
• One ultraviolet disinfection unit
• One 299,000-gallon synthetically lined storage pond
• One irrigation pump station with two 31 GPM pumps and effluent flow meter
• 3.6 acres of irrigation area consisting of eight zones and all associated piping, valves,
controls, and appurtenances.
On January 10, 2024, the WWTF received a violation for exceeding its Monthly Average Limit of
Ammonia (Tracking Number: NOV-024-LV 0046). A Special Order by Consent has been
requested to avoid any further violations while corrective actions are taken. MacConnell and
Associates, PC has been retained to evaluate and design an immediate solution.
On April 22, 2024, Gary S. MacConnell, PE and Annie Foxworth, EI visited the site to inspect
current conditions. All existing components of the treatment system appeared to be in satisfactory
condition. Review of non -discharge monitoring reports indicate that recent samplings with high
Ammonia concentrations had lower pH ranges. Flow records range from 500-1,200 GPD, less
than half the design treatment capacity. The Operator has also expressed difficulty meeting the
Ammonia limits with the WWTF's current configuration.
Based upon the WWTF's current configuration and non -discharge monitoring reports, M&A
recommends that flow equalization to be installed at the front of the system. High levels of
ammonia indicate that the EZ Treat Treatment System is overwhelmed with surges of peak flow
(which typically occurs around lunch time). When a surge of peak flow occurs, wastewater does

not receive adequate anaerobic and aerobic treatment. Detention time in the septic tanks is
shortened and the recirculation ratio of wastewater received by the EZ Treat treatment pods is
reduced. Current configurations of EZ Treat Treatment systems are typically installed with a pre -
flow equalization tank so that the recirculation tank and treatment pods are gradually dosed to
allow for a consistent 5 to 7 recirculation ratio. EZ Treat treatment systems with pre -flow
equalization have consistently shown the ability to produce reuse quality water. It is also
recommended that a calcite filter provided by EZ Treat be added to the WWTF to provide
additional alkalinity for the nitrification of ammonia. Although it is not a result of any violations,
the irrigation field's control panel has reached the end of its life and it also in need of replacement
as well. With the proposed design modifications, it can be expected that ammonia concentrations
will return to 6 mg/1, well below the Month Average Limit of 15 mg/l.
Predicted Compliance Schedule can be found in the subsequent sections of this application
package. Per the monitoring requirements of the permit, sampling for ammonia is conducted three
times a year (March, July, and November). Possible future violations would include July and
November of 2024.
