20.134.010 Purpose.

The purpose of this chapter is to establish minimum standards for the control of environmental pollution and to minimize the adverse effects of contaminants which may result from land use activities in a manner which protects the public health and general welfare.

20.134.020 Environmental performance standards.

It is the responsibility of the operator and/or proprietor of any permitted use to comply with the following environmental performance standards as set forth in this chapter. It shall further be the responsibility of the operator and/or proprietor of any permitted use to provide such reasonable evidence and technical data as the zoning administrator may require to prove compliance with this Chapter, if and when such need arises.

Proposals which require review under the regulations of the State Environmental Policy Act (SEPA) will be processed as set forth in the WAC 197-11 and Title 21 of the Walla Walla Municipal Code. No approval or permit shall be issued on the proposal until SEPA review is complete.

B. Toxic substances (including asbestos, beryllium compounds, vinyl chlorides, and benzol and any others added to the toxics list of the U.S. Environmental Protection Agency Standards). Asbestos demolition (including the handling of scrap asbestos from any source) shall be conducted in accordance with the state Department of Ecology requirements.

C. Liquid or solid wastes shall be disposed of in keeping with the best operating practices of the industry and in compliance with the regulations and requirements of local, regional, state, or federal agencies having jurisdiction in liquid or solid waste disposal and environmental health and safety.

D. Radioactive Materials and Radiation Devices. The use, transportation, storage, and disposal of all radioactive materials and handling devices shall be subject to the regulatory controls of any local, regional, state, or federal agency having jurisdiction.

E. Ground and Soil Contaminants. Materials used or created in any commercial/industrial process shall be handled in such a manner so as to prevent ground or soil contamination which destroys or endangers the support of natural vegetation or which may pollute underground aquifers or other natural drainage systems. (Ord. 2023-08 § 3, 2023).

20.134.050 Perceptual nuisance.

A. Heat or Glare. Any operation producing intense heat or glare shall be performed within an enclosure so as to completely obscure such operation from view from any point along the property line except during the period of on-site construction.

B. Lighting. Exterior lighting shall be so arranged as far as practical to reflect light away from a residential use.

C. Vibrations or Concussions. No activity or use shall cause earth vibrations or concussions detectable without the aid of instruments beyond its lot lines, with the exception of the temporary vibration produced as a result of construction activity, except as specifically permitted by City Council after a public hearing. Such temporary construction activity shall be restricted to the hours between 7:00 a.m. and 8:00 p.m. Emergency conditions, as verified by the zoning administrator, are exempt from these provisions.

20.134.060 Storage – Commercial or industrial.

In the conduct of any business, the storage of merchandise, raw materials, equipment, fixtures, scraps or solid wastes shall comply with the following requirements:

A. Inside Storage. Every reasonable effort shall be made by persons operating a business to store all such materials within an enclosed building, with the following exceptions:

1. Where such inside storage is not practical or desirable for reasons related to health, fire or safety codes; or

2. Where the outside storage of merchandise, manufactured products, or raw materials is normal and standard practice, such as in the sale of automotive equipment, mobile homes, lumber, gardening materials, nursery stock and the like, or on the site of construction projects; or

3. When materials or products are temporarily stored outside incidental to shipping, delivery, loading or unloading thereof.

B. Outside Storage.

1. Where review of a proposal indicates that inside storage is inappropriate, the outside storage of junk, used or secondhand furniture and appliances, scraps or solid wastes, construction or rental equipment, lumber or building supplies, or similar material may be permitted provided it shall be entirely enclosed within a sight obscuring fence at least six (6) feet in height, or behind a screen of dense landscaping at least six (6) feet in height, or both, as determined by the reviewing official. For screening requirements for Wrecking Yards and Junk Yards, see Section 20.110.100(B).

2. Outside storage shall be maintained in an orderly manner consistent with good housekeeping practices and shall create no visual offense to the premises, adjacent properties, or public right-of-way, or create fire, safety, or health hazard. The Site Plan Review Committee during development review may require that open storage areas be fully screened from view (for evergreen material designed to constitute a solid planting) where in its opinion a visual offense or hazard may exist as a result of the proposed commercial/industrial activity;

3. Outside storage of any commercial or industrial products in a zone abutting a residential zone is required to be screened with dense landscaping at least six (6) feet in height, of a type and spacing acceptable to the Site Plan Review Committee or other reviewing official.
