ISDS 



Until such time as necessary sewer line extensions can be made to priority areas, CRMC 

 recommends that towns implement a regular maintenance program for ISDS including, at a 

 minimum: 



a) Mandatory pumping every three years; 



b) Appropriation of funds for a maintenance program through the Sewer and Water 

 Supply Failure Fund and municipal bond issues, among other funding sources; 



c) Mandatory reporting of failed or failing systems to town authorities by septic tank 

 pumpers; 



d) Recording of system failure or uncorrected violations of state ISDS regulations on 

 property deeds, as incentive to eliminate chronic ISDS problems; 



e) Development of homeowner education programs and materials on preventive ISDS 

 maintenance, addressing such measiu^s as: 



water conservation practices; 



discouragement of garbage disposals; 



avoidance of disposal of greases and oils into household drains; 



proper disposal of chemical wastes (paints, thinners, alcohol, acids, drain 



cleaners, etc.); 



separate drainfield for washing machine discharges; 



prohibition of the use of chemical ISDS "rcjuvenators"; 



planning for alternate sites in the event of primary site failure; and 



resting part of the leachfield system periodically through design or installation 



of alternate beds. 



***In accordance with the findings and recommendations included in the ISDS Task Force 

 Report and its Subcomminee Reports, particularly as they relate to coastal critical areas, 

 amend CRMP regulatory language and all SAM plan regulatory langxiage to state clearly: 



a) speciflc site evaluation criteria to be applied by DEM and CRMC in 

 coastal areas in consideration of potential impacts to sensitive or 

 dynamic coastal systems; 



b) system design, installation, and maintenance requirements to be 

 applied in coastal areas (consistent with the objectives of the point- 

 based system described in previous sections); 



c) procedures to be used in applying a point-based system (such as that 

 described in previous sections) to evaluations of variances and 

 special exceptions; 



d) enforcement mechanisms and penalties to be applied in CRMC 

 actions against violators of CRMC permits; and 



e) CRMC permitting criteria to be applied in implementing a mandatory 

 system upgrade program (MAINTENANCE AND REPAIR above).
