any other matter or thing originating from any excavation
upon the lunds and premises, except that the suspended
solids shali not be of a size greater than 0.01 Ma, in
@iameter and the concentration of suspended solics shall
not he more than 200 parts per million."

This would therefore require that all creeks and water ~
courses shall be physically isolated from work areas and mud

banks (these occur as strata within the gravel strata) such that
water bearing either silt, clay, sand, rubble, debris, gravel or
any other matter or thing originating in the work areas or mud
banks will net enter the creeks or water courses before being
processed by purification facilities such as settling basins.

Under ‘Se recent reorganization structure that was
presented to Council, it was proposed that a Project Technologist
be enployed and that one of his main areas of concern be the
operetion of the gravel pits: this position will be covered
in a further report on staff being submitted to Council. In order for
this technolcgist to be able to determine the amount of silt
entering the natural water course from a gravel removal operation,
it would be necessary to purchase the necessary equipzent to
measure the amcunt of turbidity in the water and the particle
size. The cost of this equipment is approximately $1,250.00.

This would enable the Engineering Department to determine con-=
clusively that the violation was taking place, ‘The :deal
situation is that no silt or other fine materials be ailowed

to escape into natural water courses; this, of course, is
almost impossible, as the largest clay particles (0.005 Ma. in
diameter) setcle at only 4" per 100 minutes and it is felt that
it would be unreasonable and uneconomical to expect these
susvended solids to be removed.

In cr@er to ensure that these new standards ere met,
it is recommended that Subsection (c} of Section 5 of By-Law
1489 be revised to:

"A good and sufficient covenant under seal by the applicant,
that the applicant shall cause certain soil, sand, gravel,
rock or other substance of which land is composed to re
rezoved in accordance with the said permit and this by-law
and performance bord acceptahle to the Engineering Supez-
visor, the principal amount of Four Thousand Dollars
($4,000.00) per acre of the areas affacted by the soil
removal, including excavation areas, purification facilities,
storage areas, work areas, stockpile areas, access road
areas, parking areas and processing plant areas, but not
less than Ten Thousand Dolhars ($10,000.00) to ensure
the reroval of sand, soil, gravel, rock or other substance
of which land is composed, in accordance with the said
peraat and this by-law.“
