In the preparation and enactment of this chapter, it is recognized that there are some uses, which, because of their very nature, have operational characteristics that have a serious and deleterious impact upon residential, office and commercial areas. Regulation of the locations of these uses is necessary to ensure that the negative secondary impact that such businesses have been documented to have will not cause or contribute to the blighting or downgrading of the township's residential neighborhoods, community uses which support a residential environment, and commercial centers. The regulations in this section are for the purpose of locating these uses in areas where the adverse impact of their operations may be minimized by the separation of such uses from one another and from residential neighborhoods and places of public congregation. The provisions of this section have neither the purpose nor effect of imposing a limitation or restriction on the content of any communicative materials, including sexually oriented materials. Similarly, it is neither the intent nor effect of this section to restrict or deny access by adults to sexually oriented materials protected by the First Amendment, or to deny access by the distributors and exhibitors of sexually oriented entertainment to their intended market.

Purpose and Intent. The purpose of this ordinance is to establish a regulatory framework for siting, design, operation and decommissioning of High Resource Demand Facilities, which include data centers and data processing centers, in order to balance local economic benefits with protection of public health, safety, welfare, natural resources, and neighborhood character. These standards are intended to:
Direct High Resource Demand Facilities to locations with existing and adequate infrastructure, redevelopment and infill of existing sites, and minimal land use conflicts.
Avoid and mitigate nuisance impacts (noise, vibration, light/glare, air emissions).
Ensure efficient use of water and electricity, prioritizing renewable energy and conservation.
Promote context appropriate architectural and robust screening.
Ensure responsible decommissioning and site restoration.
Applicability.
Section 36-151 applies to High Resource Demand Facilities, Data Center and Data Processing uses, including Large-Scale, Small-Scale, and Accessory as defined herein.
Complete Special Land Use and Site Plan applications are required in accordance with Articles 36-VI and 36-VII herein.
Approval is contingent upon the applicant demonstrating conformance to the requirements of this ordinance and other standards of the Zoning Ordinance.
Where conflicts exist between this section and other provisions, this section governs. Where silent, other applicable provisions apply (e.g., lighting, landscaping, stormwater management, and performance standards).
C. Definitions.
High Resource Demand Facility (HRDF): A principal nonresidential facility, campus, or group of buildings under common ownership or control that is characterized by (i) continuous or near-continuous operation, and (ii) significant mechanical, electrical, or cooling infrastructure, that meets the applicability criteria in subsections a. and b. below.
A facility shall be considered an HRDF only when both of the following are met:
Operational Characteristics. The facility includes one or more of the following operation characteristics that are integral to the primary use:
Central plant or large-scale mechanical cooling and/or ventilation systems service process loads or IT/electronic equipment;

Dedicated electrical transformation/switchgear yard, substation, or similarly intensive electrical infrastructure primarily serving the facility;
24-hour operations and/or operational necessity requiring uninterrupted environmental control (temperature/humidity) or high-reliability power systems.
Resource/Infrastructure Thresholds. The facility exceeds one or more of the following thresholds, as demonstrated by applicant-prepared estimates and approved or constructed within five (5) years:
Water demand: average daily water demand > 100,000 gallons/day;
Sanitary sewer: average daily sanitary discharge > 50,000 gallons/day;
Electric demand: maximum contracted demand or designed peak demand > 10MW (or equivalent documented kW);
Hazardous material s/ regulated wastes: storage, use, or generation requiring reporting under [EPCRA Tier II and/or applicable state hazardous materials reporting] and/or generation of hazardous waste at a level regulated under [state/federal hazardous waste generator requirements], as documented on a materials inventory submitted with the application.
Exclusions. HRDF does not include general warehousing/distribution, general manufacturing, or office uses unless the Zoning Administrator determines, based on operational characteristics and supporting documentation, that the facility is substantially similar in operational profile to HRDF-type facilities (e.g., high-reliability power demand and continuous environmental control serving electronic/process loads) and meets subsections a. and b.
Aggregation. Multiple buildings, modules or phases located on the same site or on contiguous parcels under common ownership or control shall be aggregated for purposes of determining HRDF status and whether thresholds are exceeded.
Relationship to Data Centers. A Data Center or Data Processing Center that meets the HRDF definition shall be considered an HRDF and shall comply with all applicable HRDF supplemental standards.
