accompanying a fertilizer or soil conditioner.
Lawn Patch Product. A premixed blend of grass seed, fertilizer, and mulch.
Management Unit. An area sharing common characteristics, including soil type, nutrient content, and
plant type or crop produced, so that nutrients can be recommended and managed in a uniform and
consistent manner.
Milkhouse Process Water. Residual milk and wash water that is generated with the normal operation

land applied.
Natural Organic Fertilizer. A fertilizer product that is derived from either a plant or animal product
containing one or more elements, other than carbon, hydrogen and oxygen, which are essential for plant
growth. These materials may be subject to biological degradation processes under normal conditions
of aging, rainfall, sun-curing, air drying, composting, rotting, enzymatic or anaerobic or aerobic bacterial
action or any combination of those conditions. These materials shall not be mixed with synthetic
materials or changed in any physical or chemical manner from the material's initial state except by
manipulations such as drying, cooking, chopping, grinding, shredding, hydrolysis or pelleting.
Non-agricultural Turf or Lawn. Any non-agricultural land area that is covered by any grass species,
excluding flower or vegetable gardens, pasture, hay land, trees, shrubs, turf grown on turf farms or any
form of agricultural production or use.

USDA. United States Department of Agriculture.
Waters of the Commonwealth. All waters within the jurisdiction of the Commonwealth, including,
without limitation, rivers, streams, lakes, ponds, springs, impoundments, estuaries, wetlands, coastal

Permit Program.
Zone A. The land area between the surface water source and the upper boundary of the bank; the land
area within a 400 foot lateral distance from the upper boundary of the bank of a Class A surface water
source, as defined in 314 CMR 4.05(3)(a): Class A; and the land area within a 200 foot lateral
distance from the upper boundary of the bank of a tributary or associated surface water body, as

Zone I of a Public Water Supply Well. The protective radius required around a public water supply
well or wellfield regulated by 310 CMR 22.00: Drinking Water. For public water system wells with
approved yields of 100,000 gpd or greater, the protective radius is 400 feet. Tubular wellfields require
a 250-foot protective radius. Protective radii for all other public water system wells are determined
by the following equation: Zone I radius in feet = (150 x log of pumping rate in gpd) - 350. This
equation is equivalent to the chart in the Guidelines and Policies for Public Water Systems. A default
Zone I radius or a Zone I radius otherwise computed and determined by the Department shall be
applied to transient non-community (TNC) and non-transient non-community (NTNC) wells when
there is no metered rate of withdrawal or no approved pumping rate. In no case shall the Zone I radius
be less than 100 feet.
