[Added by Ord. No. 10-89]
There is hereby established an ASA Aquifer Sensitive Area Overlay
Zone District to provide supplemental development regulations in the
area so designated to permanently protect the source of Denville Township
water supply from additional contamination originating from man's
activities. Due to the extraordinary vulnerability and sensitivity
of the aquifer resource to contamination, these regulations contain
additional protective measures. This article, therefore, applies to
any person, firm or corporation within the ASA Overlay Zone that establishes
or proposes to establish additional land use or development activity.
The objective of the ASA - Aquifer Sensitive Area Overlay Zone
District are:
A.
To protect the aquifer from water quality degradation due to land
use changes or development activity;
B.
To define the responsibilities of implementing and enforcing land
use controls for the protection of aquifer water quality;
C.
To establish strict performance standards for use, handling, or storage
facilities or associated materials which have the potential for contaminating
the aquifer;
D.
To establish land use intensity limitations, in accordance with the
availability of sanitary sewers.
A.
The ASA - Aquifer Sensitive Area Overlay Zone District will be applicable to all areas in the Township of Denville noted to be within the sole source aquifer as identified in studies prepared by Geraghty and Miller, Inc., entitled "An Evaluation of Groundwater Resources of the Rockaway River Valley Within the Communities of Denville, Boonton Township, Town of Boonton, Montville and Mountain Lakes," dated August 1978 and the Geonics study "Water Resource Study of the Rockaway Valley," dated February 1, 1980, and as delineated by the ASA - Aquifer Sensitive Area Overlay Zone District Map, which is incorporated in § 600-143 of this chapter.
B.
The standards as provided within the ASA Overlay Zone shall be considered
more restrictive than the underlying zone, where applicable.
A.
Within an ASA Overlay Residential Zone in the Township of Denville,
any new residential development shall, as a condition of approval,
be required to connect to a central sewer system prior to occupancy,
or if sewers are not available, development shall be conditioned on
all new residential developments maintaining a minimum lot size of
three acres per dwelling unit.
B.
If public sewers are available and there is adequate sewer gallonage,
then the underlying zone regulations shall be applicable subject to
the additional regulations and performance standards provided herein.
All nonresidential development, including public and institutional
uses as a condition of approval within the Aquifer Sensitive Area
shall be required to either connect to a centralized sanitary sewer
system or utilize a closed holding tank disposal system approved by
the Department of Environmental Protection. This shall apply to any
site plan, subdivision, variance or request for a building permit.
A.
The provisions in this article are not intended to repeal, abrogate,
or annul any portion of these regulations, or existing county, state
or federal regulations. In any case where there is a conflict, whichever
imposes the more stringent restrictions shall apply.
B.
All uses that are permitted in the underlying zones shall be permitted
in the Aquifer Sensitive Area Overlay Zone with the following exceptions
and restrictions:
(1)
The disposal, storage, or treatment of hazardous and solid waste
material as defined by the New Jersey Department of Environmental
Protection.
(2)
Utilization or storage of sodium chloride salts or other road
salts other than calcium chloride salts.
(3)
Dry wells directly connecting to any floor drain, wash basin,
sink or paved parking areas.
(4)
Gasoline stations, except existing gas stations.
(5)
Underground fuel storage tanks shall be permitted subject to
the following conditions:
(a)
Any applicant proposing to install an underground fuel storage
tank shall obtain an application and permit from the Construction
Code Official and shall receive written approval and authorization
of the Fire Chief, Township Engineer and Health Officer. The applicant
shall notify the appropriate code officials at least 48 hours in advance
of all work.
(b)
All underground tanks where approved shall be double-hulled
steel or fiberglass encased in a concrete vault and shall be installed
in accordance with Uniform Construction Code.
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. III)]
(c)
When a question arises as to a proposed use (principal and/or
accessory) and its potential to degrade or contaminate the aquifers
designated for protection herein, the approving authority shall solicit
input from the state Department of Health Services. Each application
shall include any and all necessary federal or state permits.
A.
Any application for development within the Aquifer Sensitive Area
not served by a centralized sanitary sewer system shall require the
submission of an environmental impact statement. Excluded from this
requirement are all single- and two-family structures seeking building
permits and all minor subdivisions.
B.
All applicants filing an environmental impact report shall prepare
such a report in accordance with the provisions of this section. In
such instances, the report shall provide additional information to
the Township, demonstrating that the applicant can comply with all
standards of this section, or that one or more of such standards would
not be applicable, given the conditions of the applicant's property
or existing uses thereon.
C.
The format and contents of the environmental impact report shall
be as follows:
(1)
Description of existing conditions. This section shall present
a description of existing characteristics of the property with respect
to geology, topography, ground and surface water hydrology, soils,
vegetation, and existing improvements and uses.
(2)
Description of the proposed action. This section shall describe
the proposed action including types, locations and phasing of proposed
site disturbance and construction, as well as proposed future use,
ownership and maintenance of the property and the proposed improvements.
Plans describing the proposed action shall also be included within
the Environmental Impact Report.
(3)
Proposed measures to control potential adverse environmental
impacts. This section shall describe all measures proposed by the
applicant to control all adverse impacts that may occur as a result
of the proposed action. It shall address all impacts cited by the
Township Engineer and all other designated experts by the Township
in the report on the application, prepared in accordance with procedures
described herein.
(4)
List and qualification of preparers. The names, addresses, telephone
numbers and qualifications of persons directly responsible for preparing
the Environmental Impact Report shall be provided.
(5)
Appendices. Any additional information the applicant wishes
to provide may be included in one or more appendices to the report.
(6)
The Environmental Impact Report must be received by the Township
no later than 30 days prior to the date of the public hearing as required
by law. The report shall be submitted in 20 copies to the Township.
No structure, land or water shall be used or developed, and
no structure shall be located, extended, converted, or structurally
altered in the Aquifer Sensitive Area unless the applicant takes all
reasonable measures to minimize any impact of the proposed action,

shall not directly or indirectly diminish the flow of natural springs.
As required by the Environmental Impact Statement report, water table

Where by reason of extraordinary and exceptional situation uniquely
affecting a minor subdivision or a minor site plan, or the construction
of no more than two residences or for site plan for nonresidential
development of no more than 1,500 square feet, the Planning Board
may provide a waiver for some or all of the standards provided herein.
