N.J. Admin. Code § 7:14A-9.12 - Application requirements for NJPDES-DGW permits for sanitary landfills
(a) In addition to
the information required pursuant to
7:14A-4.3, an applicant for a
NJPDES-DGW sanitary landfill monitoring permit shall ensure that the Department
has in its possession maps, cross sections and reports as follows. Maps may be
combined if all required features are clearly shown.
1. A location map:
i. The site shall be located on a U.S.
Geological Survey 7.5 minute series Topographic Quadrangle. The quadrangle
shall be the most recent revision.
ii. The site shall be shown by legal
boundaries surveyed by a New Jersey licensed land surveyor indicating roadways,
adjacent property ownerships and all inhabited structures and facilities within
one half mile of site boundaries.
2. A topographic map(s):
i. The topographic map of the facility shall
have a horizontal scale of at least one inch equals 200 feet and a contour
interval of five feet. Contour elevations shall be based on established N.J.
Geological Control Survey Datum and the map shall be keyed into the New Jersey
State plane coordinate systems. The topographic map(s) shall indicate original,
existing, and proposed topography.
ii. An additional topographic map shall
indicate all surface waters within one-half mile of the sanitary landfill site
and all water supply reservoirs and public recreational bodies of water within
one mile of the landfill boundary;
3. A ground water supply map showing the
depth and location of wells within one-half mile radius and all public supply
wells or wells permitted to pump over 100,000 gallons per day or 70 gallons per
minute within 1 1/2 miles of the proposed sanitary landfill shall be plotted.
Pump capacity or diversion allocation for all wells yielding greater than 70
gallons per minute shall be reported and keyed to the map. All occupied
buildings, including private dwellings, within one-half mile radius of the
proposed sanitary landfill facility shall be plotted and identified as to type
(for example, industrial, commercial, or residential). The service areas, if
any, of municipal or community water supply systems shall be
identified;
4. A detailed geologic
map of the entire site, including all the area outside the sanitary landfill
site boundary to a distance of one-half mile. The base data for this map shall
be compiled by a geologist. The scale of the geologic map shall be at least one
inch equals 400 feet and shall show the following information:
i. Bedrock outcrops;
ii. The dip and strike of sedimentary
formations and foliation trends and dip angles of igneous and metamorphic
rocks;
iii. Fault(s) and prominent
shear zone(s) trends;
iv. Joint or
fracture trends in bedrock outcrops including dip angles;
v. The trend direction of solution channels
in carbonate rocks and sink holes;
vi. The location of any active or abandoned
mine workings; and
vii. A geologic
report describing the major characteristics of the formation(s), including
thickness, lithology, structural features, degree of weathering, and amount of
overburden;
5. Geologic
cross-section(s) and fence diagrams, preferably in three dimensions, showing
the spatial relationship of the sanitary landfill, the geology, the monitoring
wells, any other engineered site improvements, or other significant features
that influence the interpretation of analytical results and
explanations;
6. Soils map and
borings:
i. A soils map shall be submitted
with a scale of at least one inch equals 400 feet. Soils information should be
drawn from the U.S.D.A. Soil Conservation Service Report(s) with site specific
soils data determined by a soil scientist using the U.S.D.A. textural
classification system on data obtained from the required borings and other
available data.
ii. A sufficient
number of borings necessary to determine soil characteristics, depth to bedrock
(where applicable), permeability and ground water elevations shall be drilled.
Where, in the judgment of the Department, submitted information is insufficient
to adequately evaluate the site, additional and/or deeper borings, supplemented
by excavations, test pits or geophysical methods will be required.
(1) Subsurface data obtained by borings shall
be collected by split spoon drive method, shelby tube or diamond bit coring.
Auger borings are not acceptable.
(2) All borings shall be a minimum depth of
10 feet below the seasonally high water table. In no case shall borings be less
than 20 feet below the lowest elevation by the sanitary landfill.
(3) Split spoon, shelby tube and diamond bit
core samples shall be labeled and properly stored for a minimum period of one
year from the date of the permit application.
(4) Profiles shall be shown for each boring
giving the depths and texture of each soil stratum or horizon and the elevation
of any ground water or aquifer encountered, and shall include the date each
boring was taken;
7. A hydrogeologic report shall be provided
for the site and for a one-half mile radius of the proposed site. The
hydrogeologic report shall include:
i. A
piezometric map based upon stabilized ground water elevations below the site
showing direction(s) and rate(s) of ground water flow and an indication as to
whether the ground water is unconfined, confined (artesian) or both for the
proposed sanitary landfill;
ii. A
generalized piezometric map based upon available data including, but not
limited to, existing topography, surface drainage and existing well data, shall
be provided for the area within one-half mile radius of the site
boundary;
iii. A survey of wells
identified on the ground water supply map prepared pursuant to (b)3 above
including the use, approximate yield, and depth of each well; and
iv. All public water supplies and wells
capable of pumping over 70 gallons per minute or 100,000 gallons per day within
a 1 1/2 mile radius of the sanitary landfill, including an assessment of the
potential impact on those supplies by the sanitary landfill;
8. Maps showing the location of
all existing and proposed ground water monitor wells; and
9. Results of leachate generation
calculations provided by performing a water balance calculation such as the
Hydrologic Evaluation of Landfill Performance (HELP) Model, EPA/600/9-94/xxx,
U.S. Environmental Protection Agency Risk Reduction Engineering Laboratory,
Cincinnati, OH.
