What are No Discharge Areas
“No Discharge Areas” NDA designates waterways where the discharge of any waste, treated or untreated, is illegal and where only Type III MSD’s are legal.
While in an NDA locking the door to the toilet with a padlock or door handle key lock is an acceptable method of securing the Type 1 or 2 MSD. Type 3 MSD’s are recommended for long term operation in an NDA and must be secured.
