				  as specified in
				  R18-9-A201(C)(1),
				  an applicant shall, as required under
				  R18-9-A201(B)(4),
				  submit the following technical information as attachments to the individual
				  permit application:
1. A topographic map, or
				  other appropriate map approved by the Department, of the facility location and
				  contiguous land area showing the known use of adjacent properties, all known
				  water well locations found within one-half mile of the facility, and a
				  description of well construction details and well uses, if available;
2. A facility site plan showing all known
				  property lines, structures, water wells, injection wells, drywells and their

				  plan shall include all known borings. If the Department determines that borings
				  are numerous, the applicant shall satisfy this requirement with a narrative
				  description of the number and location of the borings;
3. The facility design documents indicating
				  proposed or as-built design details and proposed or as-built configuration of
				  basins, ponds, waste storage areas, drainage diversion features, or other
				  engineered elements of the facility affecting discharge. When formal as-built
				  plan submittals are not available, the applicant shall provide documentation
				  sufficient to allow evaluation of those elements of the facility affecting
				  discharge, following the demonstration requirements of A.R.S. §
											49-243(B).
				  An applicant seeking an Aquifer Protection Permit for a sewage treatment
				  facility satisfies the requirements of this subsection by submitting the
				  documents required in
				  R18-9-B202 and
				  R18-9-B203;
4. A summary of the known past facility
				  discharge activities and the proposed facility discharge activities indicating
				  all of the following:
a. The chemical,
				  biological, and physical characteristics of the discharge;
b. The rate, volume, and frequency of the
				  discharge for each facility; and
c.
				  The location of the discharge and a map outlining the pollutant management area
				  described in A.R.S. §
												49-244(1);
5. A description of the BADCT
				  employed in the facility, including:
a. A
				  statement of the technology, processes, operating methods, or other
				  alternatives proposed to meet the requirements of A.R.S. §
												49-243(B),
				  (G), or (P), as applicable. The statement
				  shall describe:
i. The alternative discharge
				  control measures considered,
ii.
				  The technical and economic advantages and disadvantages of each alternative,
				  and
iii. The justification for
				  selection or rejection of each alternative;
b. An evaluation of each alternative
				  discharge control technology relative to the amount of discharge reduction
				  achievable, site-specific hydrologic and geologic characteristics, other
				  environmental impacts, and water conservation or augmentation;
c. For a new facility, an industry-wide
				  evaluation of the economic impact of implementation of each alternative
				  discharge control technology;
d.
				  For an existing facility, a statement reflecting the consideration of factors
				  listed in A.R.S. §
												49-243(B)(1)(a)
				  through (h);
e. A sewage treatment facility meeting the
				  BADCT requirements under Article 2, Part B of this Chapter satisfies the
				  requirements under subsections (A)(5)(a) through (d).
6. Proposed points of compliance for the
				  facility based on A.R.S. §
											49-244. An
				  applicant shall demonstrate that:
a. The
				  facility will not cause or contribute to a violation of an Aquifer Water
				  Quality Standard at the proposed point of compliance; or
b. If an Aquifer Water Quality Standard for a
				  pollutant is exceeded in an aquifer at the time of permit issuance, no
				  additional degradation of the aquifer relative to that pollutant and determined
				  at the proposed point of compliance will occur as a result of the discharge
				  from the proposed facility. In this case, the applicant shall submit an Ambient
				  Groundwater Monitoring Report that includes:
i. Data from eight or more rounds of ambient
				  groundwater samples collected to represent groundwater quality at the proposed
				  points of compliance, and
ii. An
				  AQL proposal for each pollutant that exceeds an Aquifer Water Quality
				  Standard;
7.
				  A contingency plan that meets the requirements of
				  R18-9-A204;
8. A hydrogeologic study that defines the
				  discharge impact area for the expected duration of the facility. The Department
				  may allow the applicant to submit an abbreviated hydrogeologic study or, if
				  warranted, no hydrogeologic study, based upon the quantity and characteristics
				  of the pollutants discharged, the methods of disposal, and the site conditions.
				  The applicant may include information from a previous study of the affected
				  area to meet a requirement of the hydrogeologic study, if the previous study
				  accurately represents current hydrogeologic conditions.
a. The hydrogeologic study shall demonstrate:
i. That the facility will not cause or
				  contribute to a violation of an Aquifer Water Quality Standard at the
				  applicable point of compliance; or
ii. If an Aquifer Water Quality Standard for
				  a pollutant is exceeded in an aquifer at the time of permit issuance, that no
				  additional degradation of the aquifer relative to that pollutant and determined
				  at the applicable point of compliance will occur as a result of the discharge
				  from the proposed facility;
b. Based on the quantity and characteristics
				  of pollutants discharged, methods of disposal, and site conditions, the
				  Department may require the applicant to provide:
i. A description of the surface and
				  subsurface geology, including a description of all borings;
ii. The location of any perennial,
				  intermittent, or ephemeral surface water bodies;
iii. The characteristics of the aquifer and
				  geologic units with limited permeability, including depth, hydraulic
				  conductivity, and transmissivity;
iv. The rate, volume, and direction of
				  surface water and groundwater flow, including hydrographs, if available, and
				  equipotential maps;
v. The precise
				  location or estimate of the location of the 100-year flood plain and an
				  assessment of the 100-year flood surface flow and potential impacts on the
				  facility;
vi. Documentation of the
				  existing quality of the water in the aquifers underlying the site, including,
				  where available, the method of analysis, quality assurance, and quality control
				  procedures associated with the documentation;
vii. Documentation of the extent and degree
				  of any known soil contamination at the site;
viii. An assessment of the potential of the
				  discharge to cause the leaching of pollutants from surface soils or vadose
				  materials;
ix. For an underground
				  water storage facility, an assessment of the potential of the discharge to
				  cause the leaching of pollutants from surface soils or vadose materials or
				  cause the migration of contaminated groundwater;
x. Any changes in the water quality expected
				  because of the discharge;
xi. A
				  description of any expected changes in the elevation or flow directions of the
				  groundwater expected to be caused by the facility;
xii. A map of the facility's discharge impact
				  area; or
xiii. The criteria and
				  methodologies used to determine the discharge impact area.
9. A detailed proposal indicating
				  the alert levels, discharge limitations, monitoring requirements, compliance
				  schedules, and temporary cessation or plans that the applicant will use to
				  satisfy the requirements of A.R.S. Title 49, Chapter 2, Article 3, and Articles
				  1 and 2 of this Chapter;
10.
				  Closure and post-closure strategies or plans; and
11. Any other relevant information required
				  by the Department to determine whether to issue a permit.
