Other Concerns

IS THE STATE PERMIT NEEDED?

The State permit is required only if the wastes can enter the state waters directly or via a storm drainage system. If the water is discharged to the top of the roof or to landscaping and can in no way enter the storm drain or State waters (that is, it evaporates), the discharge is not considered a "point source" and a permit is not required.

ILLEGAL DISCHARGES

A "threatened discharge" is defined by the Longmont Municipal Code as any discharge of contaminants that could leave the site. (An "illegal discharge" is one that actually enters the storm sewer or State waters.) Therefore, any discharge of wastes to the roof or landscape that contains contaminants is a violation of the Municipal Code. These have the potential to leave the site during the next rain storm. The State process indicates that you do not need a permit for discharges that don't enter the storm drain, but fails to inform you of the potential violations if the wastes contains any contaminants.

BEST OPTIONS FOR CONTRACTS IN THE CITY OF LONGMONT

Collect the wastes and discharge them to the sanitary sewer on-site. Contact the IP Program at 303-651-8667.

There are no local fees for this discharge (unless the wastes is of higher pollutant strenth than domestic wastes).
There are no local applications or permits; no expiration dates to worry about. The only requirement is that the discharge meets the general and specific prohibitions of the Municipal Code. Letters of permission are available, but not required.
There is no requirement for expensive and confusing State permits.
It is the environmentally friendly option.
With no discharges to the environment, you won't have to deal with citizen inquiries or concerns about illegal or threatened discharges.
