Summary
Every use permitted in North Hempstead's Industrial B District must minimize engine idling under § 70-189.2C(9): equipment has to be shut off when not in use or held to a five-minute idling cap. The rule sits inside the district's air-pollution performance standards and is checked at building-permit and certificate-of-occupancy stage.
All uses of land in an Industrial B District shall operate in conformance with the limitations set forth in each subsection below ... C. Air pollution, smoke, dust, fumes, particulate matter, threshold values. ... (9) Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to five minutes; and

Full Breakdown
2 opens Article XX's performance standards by barring any 'dangerous, injurious, noxious or otherwise objectionable' condition from an Industrial B use, then lists limits subsection by subsection. Subsection C, covering air pollution, smoke, dust, fumes and particulate matter, requires operators to keep stockpiled fine material indoors, spray down dust with water at least twice daily outdoors, wash trucks before they leave the site, and, at item (9), minimize idling by shutting equipment off when it isn't running or capping idling at five minutes. 2 by name, a concrete-recycling operation under § 70-188B and a yard-waste acceptance and processing facility under § 70-188C, print the identical five-minute clause as a condition of their own permits.
A building-permit or certificate-of-occupancy application for a use subject to these standards must include a description of the machinery and the techniques used to keep emissions, idling included, within the limits, plus a signed affidavit agreeing to comply at all times, and the Building Commissioner can require an independent consultant's report before signing off.
Violations & Fines
Idling isn't listed among the offenses § 70-235 prices individually, so a violation of § 70-189.2 falls under the general § 70-235K schedule: up to $1,000 for a first offense, $1,000 to $2,500 for a second within five years, and $2,500 to $10,000 or up to 15 days in jail for a third, each week counted separately.
