§ 67.1-2-4. Local Limits.

The Director may impose maximum mass and/or concentration discharge limits for any pollutant, to protect the POTW from Pass tThrough or Interference and to ensure that the treatment plant complies with the objectives of Section 67.1-1-1 and applicable State and Federal law. The County has submitted technically based local limits that have been approved by the Virginia Department of Environmental Quality and hereto incorporated by reference. Industrial Users are prohibited from discharging wastewater with pollutant concentrations in excess of said limitations.

(a)

The applicable limitation(s) shall apply at the point where the wastewater is discharged into the POTW. Alternately, a User may elect to comply with local limits restrictions, measured at the end of process, in lieu of providing a monitoring facility or of separating domestic-natured wastestreams from industrial wastestreams. All concentrations for metallic substances are for "total" metal. Compliance with all parameters may be determined by the County from a single grab sample. Where specific prohibitions or limits on pollutants are developed for the POTW in accordance with this Section, such limits are deemed Pretreatment Standards.

(b)

If a National Categorical Pretreatment Standard or National Pretreatment Standard establish limitations for Industrial Users in a particular Industrial subcategory which are more stringent than the limitations specified by local limits, those more stringent limitations shall immediately apply to those Industrial Users subject to such limitations.

(c)

The Director may develop Best Management Practices (BMPs), by ordinance or in wastewater discharge permits, to implement local limits and the requirements of Section 2.1. (44-09-67.1.)
