Rule 21 Sewage and trade waste conveyance, treatment and disposal

Updated 3 July 2015 12:53pm

The discharge of contaminants into air in connection with:

(1) sewage and liquid or liquid-borne trade waste conveyance, treatment and disposal (including the operation of septic tanks and soakage pits);

is a Permitted Activity, provided it complies with the conditions below, and excluding any discharges of contaminants to air arising from processes involving:

(a) the treatment of sewage and/or liquid or liquid-borne trade wastes off the site on which it was generated (e.g., municipal sewage treatment).

Conditions

The person(s) responsible for the activity shall ensure that:

(i)there is no discharge of odour, gas, vapour or aerosol which is noxious, dangerous, offensive or objectionable at or beyond the boundary of the property.

Explanation:Rule 21 permits discharges to air in connection with the conveyance, treatment and disposal of sewage and liquid and liquid-borne trade wastes. This rule permits the discharge of contaminants to air from septic tanks and soakage fields as well as the discharge of contaminants to air resulting from the conveyancing of sewage through sewerage systems, including the pumping stations. This rule is not intended to cover the discharge of contaminants to air from the movement of wastes by vehicular transport. Such discharges from mobile sources are not controlled by this Plan. Discharges to air that are permitted by this rule must comply with the condition that they do not result in the discharge of odour, gas, vapour or aerosol which is noxious, dangerous, offensive or objectionable at or beyond the boundary of the property.

The discharge of contaminants to air arising from the treatment of municipal sewage or liquid or liquid-borne trade wastes is explicitly excluded from Rule 21 and requires a resource consent under Rule 23.
