 KEY CCAHP RECOMMENDATIONS 



Page 74 



REGIONAL LEVEL 



STATE LEVEL 



FEDERAL LEVEL 



6. Large 

 niinber of 



aging 



underground 

 storage tanks 

 in close 

 proximity 

 to publ ic 

 water 

 supplies 



- Inventory and nap 

 tanlcs 



- Utilize land use con- 

 trols to discourage 

 new tanks in Zone I Is 



- Appoint UST 

 coordinator 



- Adopt UST bylaw to 

 regulate fuel oi I 

 tanks and encourage 

 removal of tanks at 

 specified age 



Educate local of- 

 icials and public 

 Transmit research 

 findings to local 

 level 



BCHED assistance 

 program for tank 

 inventory 

 Model UST bylaw 



State should clarify 

 existing policies on 

 tank cleaning and 

 disposal 



Require stricter con- 

 struction standards 

 for tanks and piping 

 in Zone I Is. 

 Develop educational 

 materials 



Provide educational 

 •Bterials 

 Relay info on 

 successful state 

 and local prograns 

 Research new tank 

 construction and 

 other technologies 

 Research causes of 

 tank fai lure or 

 leakage 



7. Rapid growth 

 rate 0(i Cape 

 Cod leading 

 to high 

 nitrogen 

 I eliding and 

 other 

 problems 



Do build out analysis 

 Utilize CCAHP nitrogen 

 loading formula in 

 planning reviews to 

 calculate future 

 nitrate concentration 

 at wellhead 

 Zone to ensure concen- 

 trations will not 

 exceed planning goal 

 of 5 mg/L. 



Require Title 5 appli- 

 cants to demonstrate 

 that goal wi II not be 

 exceeded 



If needed, restrict 

 fertilizer use 

 Towns should consider 

 phasing growth so 

 infrastructure needs 

 can be met 



Technical assist- 

 ance to comnjnities 

 on nitrogen loading 

 fornula application 

 RPA should develop 

 regional growth 

 plan; local plans 

 should be consist- 

 ent 



- State should require 

 planning for future 

 water supplies before 

 zoning 



- Require discharge 

 permit applicants 

 (>15,000 gpd) to 

 dennnstrste <=5 mg/L 

 nitrate cone, at well 



- Revise Title 5 to 

 incorporate density 

 factor in the 

 calculation 



- Encourage/find 

 wastewater treatment 

 facilities with 

 advanced levels of 

 treatment 



- Sponsor research on 

 denitrif ication 

 technologies 



• Encourage/fund 201 

 facilities with 

 advanced levels of 

 treatment for 

 ground discharges 

 within sole source 

 aquifers 



- USGS should con- 

 tinue to research 

 the relationships 

 between land use 

 and nitrate loading
