The plans and specifications for every on-site system shall
				  be prepared as follows:
(1) Every
				system shall be designed by a Massachusetts Registered Professional Engineer or

				shall not design a system to discharge more than 2,000 gallons per day pursuant
				to 310 CMR 15.203. Any other
				agent of the owner may prepare plans for the repair of one or more components,
				excluding the soil absorption system, of a system designed to discharge not
				more than 2,000 gallons per day pursuant to
				310

				and stamped by a Massachusetts Registered Sanitarian or Massachusetts
				Registered Professional Engineer and approved by the Approving
				Authority.
(2) Every plan submitted

				least one copy submitted shall bear the original stamp and signature of the
				designer.
(3) Every plan for a new
				system or plan for the upgrade or expansion of an existing system which
				requires a variance to a property line setback distance, must also reference a
				plan which bears the stamp and signature of a Massachusetts Licensed Land
				Surveyor in accordance with M.G.L. c. 112, § 81D;
(4) Every plan for a system shall be of
				suitable scale (one inch = 40 feet or fewer for plot plans and one inch = 20

(e) location and dimensions of the system
				(including reserve area);
(f)
				system design calculations, including design daily sewage flow, septic tank
				capacity (required and provided); soil absorption system capacity (required and
				provided); and whether system is designed for garbage grinder;
(g) North arrow and existing and proposed
				contours;
(h) location and log of
				deep observation hole tests including the date of test, existing grade
				elevations marked on each test, and the names of the representative of the
				Approving Authority and soil evaluator;
(i) location and results of percolation tests
				including the date of test and the names of the representative of the Approving
				Authority and soil evaluator;
(j)
				name and approval date of the Soil Evaluator of record;
(k) location of every water supply, public
				and private,
1. within 400 feet of the
				proposed system location in the case of surface water supplies and gravel
				packed public water supply wells,
2. within 250 feet of the proposed system
				location in the case of tubular public water supply wells, and
3. within 150 feet of the proposed system
				location in the case of private water supply wells;
(l) any surface waters of the Commonwealth,
				Zone As, rivers, bordering vegetated wetlands, salt marshes, inland or coastal
				banks, regulatory floodway, velocity zone, surface water supplies, tributaries
				to surface water supplies, certified vernal pools, private water supplies or
				suction lines, gravel packed or tubular public water supply wells, and
				subsurface drains located up to 100 feet beyond the setback distances in
				310
				CMR 15.211, any leaching catch basins and dry
				wells located up to 25 feet beyond the setback distances in
				310
				CMR 15.211; and the location of any nitrogen
				sensitive area identified in
				310
				CMR 15.214 within which any portion of the
				facility or the proposed system is located as well as any nitrogen sensitive
				area up to 100 feet beyond any property line of the facility.
(m) location of water lines and other
				subsurface utilities on the facility;
(n) observed and adjusted ground-water
				elevation in the vicinity of the system;
(o) a complete profile of the
				system;
(p) a note on the plan
				listing all variances to the provisions of
				310 CMR
				15.000 sought in conjunction with the plan;
(q) the location and elevation of one
				benchmark within 50 to 75 feet of the system components which is not subject to
				dislocation or loss during construction on the facility;
(r) when pressure distribution or dosing is
				proposed, complete design and specifications of the distribution system
				proposed including but not limited to dosing chamber capacity (required and
				provided), pump curves and specifications, number of dosing cycles and depth
				per cycle;
(s) when a Recirculating
				Sand Filter or equivalent alternative technology is required or proposed, a
				complete plan and specifications for the system, including a hydraulic
				profile;
(t) a locus plan to show
				the location of the facility including the nearest existing street;
(u) the street number and lot number, if any,
				and the tax map number and lot number, if any, of the facility; and
(v) the materials of construction and the
				specifications of the system.
