            (3) Specifically, abatement includes, but is not limited to:
            (a) Projects for which there is a written contract or other documentation, which provides that an individual or firm will
be conducting activities in or to a residential dwelling or child-occupied facility that:
            (i) Shall result in the permanent elimination of lead-based paint hazards, in the case of dust-lead hazards to below the
action levels; or
            (ii) Are designed to permanently eliminate lead-based paint hazards, in the case of dust-lead hazards to below the
action levels, and are described in Subsections R307-840-2(1) and R307-840-2(2).
            (b) Projects resulting in the permanent elimination of lead-based paint hazards, in the case of dust-lead hazards to
below the action levels, conducted by firms or individuals certified in accordance with Section R307-842-2, unless such projects
are covered by Subsection R307-840-2(4);
            (c) Projects resulting in the permanent elimination of lead-based paint hazards, in the case of dust-lead hazards to

product of the sample's result multiplied by the number of subsamples in the sample, and dividing the sum by the total number of
subsamples contained in all samples. For example, the weighted arithmetic mean of a single surface sample containing 60 ug/ft2,
a composite sample of three subsamples containing 100 ug/ft2, and a composite sample of four subsamples containing 110 ug/ft2
is 100 ug/ft2. This result is based on the equation (60+(3*100)+(4*110))/(1+3+4).

the window "well."
