Activities. uses, equipment and processes existing as of January 27, 1982. that do not meet the standards set forth in sections 9.636 to. 9.662 are subject to the following requirements: (a) No use shall be changed in a manner that could result in a greater degree of nonconformity. -(b) Expansions an~ installation of new equipment or processes sha 11 conform to app 1 i cab 1 e standa rds as set forth i n s.ecti ons 9.636 to 9.662. . (c) Time limits on existing use noise emissions that exceed stipulated maximums are prescribed in section 9.644(b). (d) All uses not otherwise prescribed by this ordinance sha 11 conform to app 1 i cab 1 e federa 1, state, and 1 oca 1 1 aws and regulations.

Act i vi ties, uses, equipment and processes estab 1 i shed after January 27. 1982. shall observe the following requirements: (a) Applicable standards as set forth in sections 9.636 to 9.662. When federal or state standards are more strict. they shall be observed. (b) Prior to issuance of a building permit or certificate of occupancy, the building official may require: 1. Evidence that mandatory federal. state. and local permits have been obtained. 2.

(Section 9.640 added by Ordinance No. .18915. enacted January 27. 1982.) 9.642 Measurements. Accurate and representati ve measurements as necessary shall be made according to accepted engineering practice. Measure- ments sha 11 be made at or anywhere beyond the property 1 i nes :of the property from which the emission is generated. (Sections 9.642 added by Ordinance No. 18915, enacted January 27, 1982.) 9.644 Noise. In addition to applicable provisions in Chapter 4 of this code. maxi mum sound em; ss; ons sha 11 not exceed equi va 1 ent sound pressure levels in decibels, A-Weighted Scale, for anyone hour as stipulated in the table in this section. These maximums are applicable beyond any property lines of the property containing the noise. Equivalent sound pressure level (Leq) is a measure of the sound level for anyone hour. It is the energy average of all the various sounds emitted from the source during the hour. A-Weighted Scale is used to adjust sound measurements to simulate the sensitivity of the human ear. .I '.....::- 9-207 12/23/93
