A. Monitoring Requirements:
The submitted Minor Modification request for Permit WQ0002708 states that the IDEXX Colilert
18 method for Fecal Coliform should be included for the facility. However, the IDEXX Colilert 18
method is not an accepted method for Non -Discharge permits. To include this method in the permit,
the applicant should request Alternative Design Criteria (ADC) in accordance with 15A NCAC
02T .0105(n). This rule states that the Director shall approve ADC if the applicant can demonstrate
that the alternative will provide:
➢ Equal or better treatment of the waste;
➢ Equal or better protection of the waters of the state; and
➢ No increased potential for nuisance conditions from noise, odor, or vermin.
