				sources that is of a similar quality (constituents and strength) to that
				produced by these same ordinary living uses.
F.
Drywell.
A well, other than a
				subsurface wastewater disposal system, completed above the water table so that
				its bottom and side are typically dry except when receiving fluids.
G.
Fluid.
Any material or
				substance that flows or moves whether in a semisolid, liquid, sludge, gas, or
				any other form or state.
H.
Formation.
A body of consolidated or unconsolidated rock with
				similar lithologic characteristics that is prevailingly, but not necessarily,
				laterally continuous and is mappable on the earth's surface or traceable in the
				subsurface.

				waste.
For the purposes of this chapter, hazardous wastes are those
				substances identified as hazardous by the Board in 06-096 CMR 850(3).
J.
Holding tank.
A closed,
				liquid-tight structure designed and used to receive and store wastewater for
				ultimate disposal at another site. A holding tank may not discharge wastewater
				to surface or groundwater or onto the surface of the ground. Holding tanks must
				be physically and chemically compatible with the contents of the
				wastewater.
K.
Home
				occupation fish or shellfish processing.
The performance of fish or
				shellfish processing work at a single-or multi-family residence where the use

				with the fish or shellfish processing work.
L.
Non-domestic wastewater.
Wastewater from commercial, industrial or residential sources that has
				constituents unlike that of or of significantly higher strength than that of
				domestic wastewater.
M.

				or matter in water. Refer to 38 M.R.S.A. §361-A(4-A) for a detailed
				definition.

Radioactive
				waste.
Any waste containing radioactive material that emits ionizing
				radiation spontaneously in concentrations that exceed those listed in 10 C.F.R.
				Part 20, Appendix B, Table II, Column 2.

Q.
Subsurface
				wastewater disposal system.
Also known as a septic system or subsurface

				to: septic tanks; disposal fields; pretreatment filters, piping, or any other
				fixture, mechanism, or apparatus used for those purposes.
R.
TSS.
Total suspended solids.
				The total of all settleable and nonsettleable solids in a sample of wastewater
				or other fluid, measured in milligrams per liter by weight.
S.
Well.
Also known as injection
				well. A bored, drilled or driven shaft whose depth is greater than the largest
				surface dimension, whether the shaft is typically dry or contains liquid; or a
				dug hole whose depth is greater than the largest surface dimension; or a
				subsurface wastewater disposal system. This definition specifically excludes
				retention basins, lagoons or any ditch or dug hole that is wider than it is
				deep.
T.
Well
				injection.
The subsurface discharge of fluids into or through a
				well.
