Current through Vol. 41, No. 20, July 1, 2024
(a)
General
				plans.
Applicants shall submit to DEQ two (2) copies of general plans
				that include the following:
(1)
Plan
				view.
Include a plan view of the plant and any discharge points, using
				at least 10- foot contours.
(2)
Flood elevations.
Show both the 25-year and 100-year flood
				elevations and their boundaries.
(3)
Existing and proposed treatment
				works.
Show the physical arrangement of all treatment units on a project
				site plat.
(4)
Existing
				collection systems.
Show the location, size and direction of flow of all
				existing sanitary sewers at the point of connection with proposed new sanitary
				sewers. Show the elevations of all sewer inverts close to the
				manholes.
(5)
Proposed
				collection systems.
Show the location of all proposed sewers, sewer
				easements and direction of flow. Number all manholes on the layout and
				correspondingly on the profile. Provide a summary of quantities that includes,
				at a minimum, linear feet of trenching, number of manholes, size, materials and
				linear feet of piping, types of testing and number and size of pumps (if
				applicable).
(6)
Existing and
				proposed reclaimed water distribution systems.
Show the location, size,
				and direction of flow of all existing and proposed reclaimed water distribution
				lines from the point of connection with the existing or proposed treatment
				works or storage locations to the end user. Provide a summary of quantities for
				proposed reclaimed water distribution lines that includes, at a minimum, pipe
				size, materials and linear feet of piping, types of testing and the number and
				size of pumps. Testing specifications shall include requirements for flushing
				mains to remove any construction debris before placing the system into service.
				Construction of reclaimed water distribution systems shall be in accordance
				with OAC 252:626-19-2, except as follows:
(A) locate reclaimed waterlines at least 5
				feet horizontally from any existing or proposed potable waterlines;
(B) locate reclaimed waterlines at least 5
				feet horizontally from any existing or proposed sewer lines;
(C) locate reclaimed waterlines crossing any
				existing or proposed potable waterlines at least 2 feet vertically below the
				potable waterlines; and
(D) locate
				reclaimed waterlines crossing any existing or proposed sewer lines at least 2
				feet vertically above the sewer lines.
(7)
Drawings.
Show the name of
				the municipality, sewer district, or institution; scale in feet; north point;
				date; and name, telephone number, address, signature of engineer and/or imprint
				of engineer's seal on the drawings. In the case of bound documents, engineers
				must affix their seal, signature and date to the cover sheet or index page,
				which identifies all documents bound together for which the registrant has
				responsible charge. In the absence of a cover sheet or index page each sheet
				must have the seal, and dated signature of the registrant who has responsible
				charge. For bound documents involving multiple registrants, either each
				document in the bound set must be sealed, signed and dated by the registrant in
				responsible charge for that portion of the work, or the cover sheet or index
				page must be sealed, signed and dated by each registrant with a breakdown of
				responsibility for each document clearly identified. Draw general plans to a
				scale of 100 feet per inch. Establish and reference a permanent benchmark. The
				minimum plan size must be 11" x 17", one-sided and of adequate contrast
				sufficient for electronic imaging and storage.
(8) Authorized design-build projects must
				label cover documents prominently as "Design-Build" specify the design package
				number, and reference the approved engineering report
				number.
