all matter of any nature excepting only storm or surface water as herein authorized," and specifically ties construction-site sedimentation control back to the county's soil erosion ordinance. The director exempts narrow categories such as water line flushing, unpolluted groundwater infiltration, potable water line discharges, air conditioning condensation, individual residential car washing, and firefighting flows (§ 30-69(b)). Anyone responsible for an accidental discharge must notify the public works or community development department within 24 hours of the nature, quantity, and time of the release and take immediate steps to contain and stop it (§ 30-69(c)).

Section 30-70 separately bars illicit connections, piping anything but stormwater or an approved discharge into the county system, and requires improper connections to be disconnected and, where possible, redirected to the sanitary sewer at the violator's cost. Maintenance duties fall on the property owner: stormwater facilities serving a single lot, subdivision, or commercial/industrial development are privately owned and maintained unless the county has formally accepted them (§ 30-71(a)-(b)). The director may inspect any property with notice (except in emergencies) and, if a facility poses an immediate danger from unsafe conditions or improper maintenance, the county may step in to make it safe and bill the owner (§ 30-71(g)).

Variances from the article's requirements require a written request showing extraordinary site-specific hardship not caused by the owner, reviewed by the director within 30 working days, with appeal to the board of commissioners (§ 30-73).
