Town of Walpole, New Hampshire

 

Adopted by Town Vote March 2004

Amended March 2008

 

TOWN WELL SOURCE PROTECTION ORDINANCE

 

SECTION 1.  PURPOSE AND AUTHORITY

 

A.      Pursuant to the authority granted under RSA 674:16, in particular RSA 674:16, II relative to innovative land use controls, the Town of Walpole hereby adopts the following regulation.  The purpose of this ordinance is in the interest of public health, safety and general welfare, to protect, preserve and maintain existing and potential groundwater supply and groundwater recharge areas within the known aquifer from adverse development, land use practices or depletion.  This is to be accomplished by regulating the uses of land over certain known aquifers and their recharge areas so as to protect them from contamination caused by adverse or incompatible land use practices or developments.  The Town Well Source Protection District Ordinance is intended to limit the uses of land so designated to those that will not adversely affect water quality by contamination or water quantity by preventing recharge of the aquifer.

 

B.      The Town of Walpole has adopted a “Source Protection Plan” to oversee the protection areas around the “Watkins Hill Well” and the “River Well”.  The Plan is to be reviewed annually and updated every 3 years by the Walpole Source Water Protection Steering Committee.

 

SECTION 2.  DISTRICT LOCATION.

 

A.      The extent of the Town Well Source Protection Districts shall follow the Well Head Delineation Area as defined by the NH Department of Environmental Services shown on the Aquifer Map included in the Walpole Source Protection Plan.

 

B.      Incorrectly Designated Zones:  Upon any well founded information that the actual boundary of the Aquifer Protection District is incorrectly mapped, the Planning Board or the owner of any land may engage a professional geologist or hydrologist or other professional, recognized by the Planning Board as being qualified to perform such work, to determine more accurately the precise boundary of the Aquifer Protection District.  The Planning Board may, based upon appropriate findings and evidence, adjust the boundary or area designation of the Aquifer Protection District or reduce or expand the designation area to more correctly define the location and the extent of the aquifer on a site-specific, case by case basis. 

 

SECTION 3.  PROHIBITED USES

 

The following uses shall not be permitted in the Town Well Source Protection Districts:

 

A.      Disposal of solid waste.  Brush and stumps are acceptable only if generated from clearing land and buried on the same site.  A copy of the site plan which is required to be filed with the Commissioner of the Department of Environmental Services, in accordance with RSA 149-m for on site burial of stumps, must be submitted to the Planning Board for its files.

1.

B.      Subsurface storage of petroleum and other hazardous materials.  Above ground storage of petroleum and other hazardous materials over 1100 gallons.

 

C.      Disposal of liquid or leachable wastes, except from single or multi-family residential subsurface disposal systems, spreading animal manure using Best Management Practices or approved commercial or industrial systems which discharge human waste only.

 

D.      Industrial uses which discharge contact type process waters on site.  Non-contact cooling water is permitted. 

 

E.      Storage of road salt or salted sand.

 

F.      Dumping of snow containing de-icing chemicals brought from outside the Town Well Source Protection Districts.

 

G.      Commercial animal feedlots.

 

H.      Mining except for earth excavation carried out in compliance with the Town of Walpole’s Regulation Governing Earth Excavation including any subsequent amendments and a Conditional Use Permit issued under Section 4 of this Ordinance and RSA 155-E.

2.      Multi-family residential development.

 

 

2

 

3.      Sand and gravel excavation carried out in compliance with the Town of Walpole’s Regulation Governing Earth Excavations including any subsequent amendments, provided that such excavation is not carried out within 8 vertical feet of the seasonal high water table and that periodic inspections are made by the Zoning Board of Adjustment or its agent to determine compliance.

 

 

B.     Standards:

 

The Planning Board may grant a Permit for a conditional use only after written findings of fact are made that all of the following are true:

 

1.      The proposed use will not detrimentally affect the quality of the groundwater contained in the aquifer by directly contributing to pollution or by increasing the long-term susceptibility of the aquifer to potential pollutants;

 

 2.     The proposed use, either alone or on a cumulative basis, will not cause a significant reduction in the long-term volume of water contained in the aquifer or in the storage capacity of the aquifer.

 

 3.     The proposed use will discharge no waste-water on site other than that typically discharged by domestic waste water disposal systems and will not involve on-site storage or disposal of toxic or hazardous material as herein defined;

 

 4.     Sufficient recharge to the aquifer will not be inhibited or prevented; and any use that covers over 20% of the lot with impervious material shall submit a “Stormwater Management Plan” that satisfies the Planning Board requirements and the Best Management Practices for Urban Stormwater Runoff, per current NH DES regulations.

 

 5.     The proposed use complies with all other applicable sections of this Ordinance.

 

The Planning Board may require that the applicant provide data reports prepared by a professional engineer or qualified groundwater consultant to assess any potential damage to the aquifer that may result from the proposed use.  The Planning Board shall engage such professional assistance as is required to adequately evaluate such reports and to evaluate, in general, the proposed use in light of the above criteria.  Costs for any of the above mentioned services shall be paid by the applicant.

 

 

SECTION 5.  ENFORCEMENT

 

It shall be the duty of the Board of Selectmen or its authorized agent to enforce the provisions of this Ordinance and to see that its requirements and restrictions are duly complied with.  A Conditional -Use Permit may be withdrawn by the Board of Selectmen if the use is not conducted in accordance with the regulations of this Ordinance or the conditions of the permit after a public hearing.

The Board of Selectmen or its authorized agent shall institute or cause to be instituted, in the name of the Town, any and all actions, legal and equitable, that shall be appropriate or necessary for the enforcement of the provisions of this Ordinance.
