Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 9 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER POLLUTION CONTROL › Article 2 - AQUIFER PROTECTION PERMITS - INDIVIDUAL PERMITS › Part B - BADCT FOR SEWAGE TREATMENT FACILITIES › Section R18-9-B202 - Design Report

Current through Register Vol. 30, No. 28, July 12, 2024
A. A person
				  applying for an individual permit shall submit a design report signed, dated,
				  and sealed by an Arizona-registered professional engineer. The design report
				  shall include the following information:
1.
				  Wastewater characterization, including quantity, quality, seasonality, and
				  impact of increased flows as the facility reaches design flow;
2. The proposed method of disposal, including
				  solids management;
3. A description
				  of the treatment unit processes and containment structures, including diagrams
				  and calculations that demonstrate that the design meets BADCT requirements and
				  will achieve treatment levels specified in
				  R18-9-B204
				  through
				  R18-9-B206,
				  as applicable, for all flow conditions indicated in subsection (A)(9). If soil
				  aquifer treatment or other aspects of site conditions are used to meet BADCT
				  requirements, the applicant shall document performance of the site in the
				  design report or the hydrogeologic report;
4. A description of planned normal
				  operation;
5. A description of key
				  maintenance activities and a description of contingency and emergency operation
				  for the facility;
6. A description
				  of construction management controls;
7. A description of the facility startup
				  plan, including pre-operational testing, expected treated wastewater
				  characteristics and monitoring requirements during startup, expected time-frame
				  for meeting performance requirements specified in
				  R18-9-B204,
				  and any other special startup condition that may merit consideration in the
				  individual permit;
8. A site
				  diagram depicting compliance with the setback requirements established in
				  R18-9-B201(I)
				  for the facility at design flow, and for each phase if the applicant proposes
				  expansion of the facility in phases;
9. The following flow information in gallons
				  per day for the proposed sewage treatment facility. If the application proposes
				  expansion of the facility in phases, the following flow information for each
				  phase:
a. The design flow of the sewage
				  treatment facility. The design flow is the average daily flow over a calendar
				  year calculated as the sum of all influent flows to the facility based on Table
				  1, Unit Design Flows, unless a different basis for determining influent flows
				  is approved by the Department;
b.
				  The maximum day. The maximum day is the greatest daily total flow that occurs
				  over a 24-hour period within an annual cycle of flow variations;
c. The maximum month. The maximum month is
				  the average daily flow of the month with the greatest total flow within the
				  annual cycle of flow variations;
d.
				  The peak hour. The peak hour is the greatest total flow during one hour,
				  expressed in gallons per day, within the annual cycle of flow
				  variations;
e. The minimum day. The
				  minimum day is the least daily total flow that occurs over a 24-hour period
				  within the annual cycle of flow variations;
f. The minimum month. The minimum month is
				  the average daily flow of the month with the least total flow within the annual
				  cycle of flow variations; and
g.
				  The minimum hour. The minimum hour is the least total flow during one hour,
				  expressed in gallons per day, within the annual cycle of flow variations;
				  and
10. Specifications
				  for pipe, standby power source, and water and sewer line separation.
