G. 
Floodway encroachment.
(1) 
In Zones A, A1-30, and AE, along watercourses that have not had a regulatory floodway designated, the best available federal, state, local, or other floodway data shall be used to prohibit encroachments in floodways which would result in any increase in flood levels within the community during the occurrence of the base flood discharge.
(2) 
In Zones A1-30 and AE, along watercourses that have a regulatory floodway designated on the Town's/City's FIRM or Flood Boundary and Floodway Map encroachments are prohibited, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base flood discharge.
H. 
Unnumbered A Zones. In A Zones, in the absence of FEMA BFE data and floodway data, the Building Department will obtain, review and reasonably utilize base flood elevation and floodway data available from a federal, state, or other source as criteria for requiring new construction, substantial improvements, or other development in Zone A and as the basis for elevating residential structures to or above base flood level, for floodproofing or elevating nonresidential structures to or above base flood level, and for prohibiting encroachments in floodways.
I. 
Drainage requirements in AO and AH Zones. Within Zones AO and AH on the FIRM, adequate drainage paths must be provided around structures on slopes, to guide floodwaters around and away from proposed structures.

(2) 
Location. Where the premises are partially outside of the Lake Watershed Protection District, such potential pollution sources as on-site waste disposal systems shall, to the degree feasible, be located outside the District.
(3) 
Disposal. Provisions shall be made to assure that any waste disposed on the site shall contain no hazardous materials, or shall be disposed in strict accordance with 310 CMR 30, Hazardous Waste Regulations.
(4) 
Drainage.
(a) 
Provision shall be made for on-site recharge of all stormwater runoff from impervious surfaces unless, in cases where such surfaces are no more than 15% of lot area or 2,500 square feet, whichever is larger, the Planning Board in conducting Site Plan Review and following consultation with the Conservation Commission, determines that either recharge is infeasible because of site conditions or is undesirable because of uncontrollable risks to water quality from such recharge following consultation with the Conservation Commission.
(b) 
Recharge shall be by surface infiltration through vegetative surfaces unless otherwise approved by the Planning Board following consultation with the Conservation Commission. Dry wells shall be used only where other methods are infeasible and shall employ oil, grease, and sediment traps. Drainage from transfer areas for hazardous materials shall be separately collected for safe disposal.
(5) 
Sewerage. Sanitary sewers within the Lake Watershed Protection District shall be designed and constructed in a manner such that groundwater levels, flows, and/or recharge will not be significantly lowered, diverted, or otherwise altered by such construction, and that risk of leakage is minimized.
D. 
Special permits.
(1) 
Authority and procedure. The Special Permit Granting Authority (SPGA) shall be the Planning Board. Upon receipt of the Special Permit application, the SPGA shall transmit one copy each to the Board of Appeals, Conservation Commission, Board of Health, and the Building Inspector for their written recommendations. Failure to respond within 35 days of transmittal shall indicate approval by said agencies.
(2) 
Submittals. In applying for a Special Permit under this Section, the information listed below shall be submitted, unless the SPGA, prior to formal application, determines that certain of these items are not germane:
(a) 
A complete list of all hazardous materials to be used or stored on the premises, accompanied by a description of the measures proposed to protect all storage containers or facilities from vandalism, corrosion, and leakage, and to provide for control of spills.
(b) 
A description of potentially hazardous wastes to be generated, including storage and disposal methods.
(c) 
Evidence of qualified professional supervision of design and installation of any proposed storage facilities or containers for hazardous materials or waste.
(d) 
For disposal on-site of domestic wastewater with an estimated sewage flow greater than 10,000 gpd per Title 5, evidence of qualified professional supervision of design and installation, including an assessment of nitrate or coliform bacteria impact on groundwater quality.
(3) 
Special permit criteria.
(a) 
Special Permits under Subsection D shall be granted only if the SPGA makes the following determinations:
[1] 
If on-site disposal is the reason a special permit is required [Subsection B(2)(b), (c) and (d)], that for the portion of the site within the Lake Watershed Protection District, nitrate loading would not exceed 10 parts per million based upon the following estimates, or other figures approved for the specific project:
Sewage volume based on realistic estimate (not simply design volume as required under Title 5).
Rainfall = 42 inches.
Fertilizer adds 0.6 pounds of nitrates per 1,000 square feet of lawn or garden.
Nitrate concentrations:
Leachate effluent = 40 ppm.
Pavement runoff = 3.0 ppm.
Roof runoff = 0.75 ppm.
Natural area recharge = 0.05 ppm.
Recharge percentages:
Leachate effluent = 95%.
Pavement and roof = 95%.
Natural and fertilized areas = 45%.
and also that for other contaminants, similar analysis would indicate groundwater meeting all standards for drinking water (310 CMR 22.00).
[2] 
That no public or private well located off-site will be degraded below State drinking water standards as a result of development on this site, for which determination the delineation of water table contours and future contaminant plumes may be required;
[3] 
That proposed control and response measures adequately and reliably mitigate risk to groundwater quality resulting from accident or system failure.
(b) 
In its written decision the SPGA shall explain any departures from the recommendations of other Town agencies.
(c) 
The Special Permit Granting Authority may retain qualified experts at the reasonable expense of the applicant if necessary in order to evaluate the application.
(4) 
Conditions. Special permits shall be granted only subject to such conditions as necessary to assure adequate safeguarding of water quality, which may include the following, among others:
(a) 
Monitoring wells to be located downgradient of potential pollution sources, with periodic sampling to be provided to the Board of Health at the owner's expense.
(b) 
Pollutant source reduction, including limitations on use of parking area de-icing materials and periodic cleaning or renovation of pollution control devices, such as catchbasin sumps.
E. 
Violations. Written notice of any violation shall be provided to the owner of the premises, specifying the nature of the violation and specifying a time for compliance including cleanup of any spilled materials which is reasonable in relation to the public health hazard involved and the difficulty of compliance, but in no event shall more than 30 days be allowed for either compliance or finalization of a plan for longer-term compliance.
