APPENDIX K - CCAMP UST RECOMMENDATIONS

Several zoning techniques that are particularly well suited include: 

 special use zoning, performance zoning, and incentive zoning. 



7 . Encourage Replacement of Old Tanks. 



It is important to encourage the removal of old tanks and others that 

 may be leak-prone such as bare steel, single-walled tanks. An effort 

 of this sort should concentrate on Zones of Contribution to public 

 supply wells or on highly dense private well clusters. A local bylaw 

 requiring mandatory removal of tanks over 20 years old that do not 

 meet new construction standards is the most direct means of meeting 

 this objective. This should be done in conjunction with a system that 

 tracks tank age and enforces the removal requirement. Another option 

 is passage of a bylaw that requires tightness testing for residential 

 tanks on a similar schedule to that required under State regulations - 

 annually after 20 years. The high cost of annual testing may serve to 

 encourage the removal of tanks greater than twenty years of age. (See 

 Table 2 for cost information.) 



8 . Discourage Placeinent of Residential Fuel Oil Tanks Underground. 



To aid in detecting leaks, home heating oil tanks and other tanks 

 containing less volatile products should be above ground whenever 

 possible. New residential tanks should be required above ground as a 

 condition placed on development or as a performance standard. 



9. Provide Financial Resources to Ensure Program Implementation. 



State regulations permit towns to charge up to $200 for each permit. 

 A tank registration fee, permit renewal fee, and tank removal fee are 

 all examples of fees that may be instituted. Towns have been slow to 

 take advantage of this due to the administrative burden of fee 

 collection. However, it is an excellent mechanism for raising money 

 for program implementation. It could also have the advantage of 

 discouraging certain types of tanks from being placed or remaining 

 underground. A permit renewal fee for tanks 20 years old and older, 

 and a registration fee for residential fuel -oil tanks placed below 

 ground are examples of revenue raising mechanisms that also discourage 

 undesirable activities. 



CCAMP RECOMMENDATIONS FOR IMPROVEMENTS TO THE STATE UST PROGRAM . 



10. Construction Requirements In Sole Source Aquifers . 



DPS should require specified protection for piping ( i.e. . 

 double-walled piping or suction pumps) in addition to the strict 

 construction standards which are specified for tanks in sole source 

 aquifers. Waste-oil and fuel-oil tanks should NOT be exempt from the 

 above construction requirements in sole source aquifers. (See 527 CMR 

 9.16 (1). (3))
