What are single event violations?
Single event violations are violations of the CWAâ€™s NPDES requirements that are documented during a compliance inspection, reported by the facility, or determined through other compliance monitoring methods by the permitting authority. Examples of single event violations include failure to obtain required permit, sampling wastewater in an unauthorized location, or an unauthorized wastewater bypass or discharge. Single event violations do not include violations generated automatically by either PCS or ICIS (e.g., effluent limit violation from a DMR, or compliance schedule violations).
