(3)

Smoke and particulate matter. Any use established in the M-1 restricted manufacturing district after the effective date of the ordinance from which this chapter is derived hereof shall be so operated as to comply with the performance standards governing smoke and particulate matter set forth in this section. No use lawfully established on the effective date of the ordinance from which this chapter is derived hereof shall be so altered or modified as to conflict with, or further conflict with, the performance standards governing smoke and particulate matter established in this section.

a.

Any use lawfully established on the effective date of the ordinance from which this chapter is derived shall be permitted to be altered, enlarged, expanded or modified; provided, that new sources of smoke or particulate matter conform to the performance standards established as follows:

1.

The total emission weight of particulate matter from all sources within the boundaries of the lot shall not exceed the net amount permitted in the M-1 district after such alteration, enlargement or modification.

2.

In addition to the performance standards specified herein, the emission of smoke or particulate matter in such manner or quantity as to be detrimental to or endanger the public health, safety, comfort or welfare is hereby declared to be a public nuisance and shall henceforth be unlawful.

3.

For the purpose of grading the density of smoke, the Ringelmann chart, published by the United States Bureau of Mines, shall be employed. The emission of smoke or particulate matter of a density greater than number two on the Ringelmann chart is prohibited at all times, except as otherwise provided herein.

4.

The emission from all sources within any lot area, of particulate matter containing more than ten percent by weight of particles having a particle diameter larger than 44 microns is prohibited.

Maximum limits. The following shall be the performance standards maximum limits for the M-1 district:

1.

In the M-1 restricted manufacturing district, the emission of more than 20 smoke units per hour per stack is prohibited, including smoke of a density in excess of Ringelmann number two. However, once during any six-hour period, each stack may emit up to 35 smoke units not to exceed Ringelmann number two when blowing soot or cleaning fires. Only during fire-cleaning periods, however, shall smoke of Ringelmann number three be permitted, and then for not more than four minutes per period.

2.

The rate of emission of particulate matter from all sources within the boundaries of any lot shall not exceed a net figure of one pound per acre of lot area during any one hour, after deducting from the gross hourly emission per acre the correction factor set forth in the following table:

ALLOWANCE FOR HEIGHT OF EMISSION
(interpolate for intermediate values not shown)

Height of Emission Above Grade (feet) Correction (pounds per hour per acre)
50 0.01
100 0.06
150 0.10
200 0.16
300 0.30
400 0.50

 

c.

Determination of total net rate of emission of particulate matter within the boundaries of any lot shall be made as follows:

1.

Determine the maximum emission in pounds per hour from each source of emission and divide this figure by the number of acres of lot area, thereby obtaining the gross hourly rate of emission in pounds per acre.

2.

From each gross hourly rate of emission deduct the correction factor (interpolating as required) for height of emission set forth in the table, thereby obtaining the net rate of emission in pounds per acre per hour from each source of emission.

3.

Add together the individual net rates of emission to obtain the total net rate of emission from all sources of emission within the boundaries of the lot. Such total shall not exceed one pound per acre of lot area during any one hour.

(4)

b.

Limits. In the M-1 restricted manufacturing district, no activity or operation shall cause, at any time, the discharge of matter across lot lines in such concentration as to be noxious. The emission of matter in such quantities as to be readily detectible as an odor at any point along lot lines is prohibited.
