Mr. Basinger,

MOORESVILLE REGIONAL OFFICE
Thank you for allowing Seven Cedars Mobile Home Park the opportunity to respond to the Notice of Violation dated
April 6, 2022; received April 18, 2022. Our response below is in regard to the (1) TSS daily maximum exceedance event
that occurred during the February 2022 monitoring period.
On February 23, the plant received a TSS result of 62 mg/L, exceeding the daily maximum allowable limit of 45 mg/L.
On this date, a heavy rainfall event created high flow conditions that surged the plant and disturbed the solids. In contrast
with flow data from the previous weeks (ranging from 0.0028 - 0.0036 MGD), the plant received 0.0072 MGD of flow on
this day. Because the abrupt increase in flow disturbed the solids, the concentrations of TSS in the effluent were
increased. Following this event, operators responded by conducting wasting to ensure that no further TSS exceedances
could occur. No subsequent noncompliance events relating to this incident have since occurred. The plant was otherwise
within compliance for the remainder of February.
It is always our goaLto remain in compliance with regulations set forth by the Division of Water Resources. The factors
contributing to this violation have been addressed carefully to prevent future noncompliance events. It is our request that
our cooperation and action in these matters be taken into account by the Division when proceeding with enforcement.
