The UUCP is now fully compliant with all dust control requirements for the Town of Paradise Valley!
On July 8, 2008, the UUCP received a letter from the Town of Paradise Valley (ToPV) concerning our unpaved (northwest) parking lot. An unpaved parking lot is required to have a stabilized surface.
Per Section 8-11-6 of the ToPV Code:
All owners/operators of an existing unpaved commercial parking lot shall stabilize the surface area(s) of the lot on which vehicles enter and park by implementing one of the following measures after first obtaining approval of the Town Engineer or designee: (l) pave; (2) apply chemical/organic stabilizers in sufficient concentration and frequency to maintain a stabilized surface; or (3) apply and maintain surface gravel uniformly to stabilize the surface.
All owners/operators shall maintain parking, maneuvering, ingress and egress areas at developments other than residential buildings with four or fewer units with one or more of the following dustproof paving methods:
On June 14, 2007, the ToPV Mayor and Council signed Resolution 1150 “…to implement measures in the MAG 2007 Five Percent Plan for PM10 for the Maricopa Nonattainment Area.” Measure 31 of the Maricopa Association of Governments (MAG) plan addresses the five unpaved parking lots in the ToPV. It specifically requires that an enforcement program is to be implemented by January 1, 2008. The plan further “…require(s) application of dustproofing to existing unpaved commercial parking lots within two years.”
As an interim measure to meet this requirement, the UUCP has stabilized the northwest parking lot in May 2010 with Tall Oil Pitch (T.O.P.) as distributed by EnsSolutions Inc.
Tall oil pitch is the dark bottom fraction of the distillation of crude tall oil, produced by the sulfate pulping process. The Sulfate
Process uses Southern Pine trees as its primary source of wood pulp due to its high resin content.
The T.O.P. product is a pitch-in-water emulsion. Because pitch is insoluble in water and extremely viscous in its
natural state, it must be emulsified to facilitate its handling and usage. Through emulsification it becomes an extremely fine dispersion of pitch particles in water. This allows for ease of dilution and fine application controls, while promoting penetration and coating of aggregate materials. The Material Safety Data Sheet for T.O.P. is available on request. The T.O.P. will be reapplied every 3-6 months as needed to preserve the surface and maintain the dust protection.
On June 14, 2010, the UUCP received notification from the Town of Paradise Valley that we are now in compliance with the MAG 2007 Five Percent Plan for PM10 for the Maricopa Nonattainment Area.
For the longer term, the UUCP Master Plan specifically addresses the “Northwest parking lot with new west side driveway entrance, concrete walk along 40th Place, asphaltic concrete drive and parking spaces, concrete accessible spaces with logos and signs, concrete wheel stops, new pole lighting, directional signage/maps, and existing electrical pit equipment corrective work” along with a “New monument sign fronting on Lincoln Drive.” Due to financial considerations, it was not included as part of the original Phase I plan. This work will make us fully compliant with the MAG 2007 Five Percent Plan for PM10 for the Maricopa Nonattainment Area.
The graphic on this page shows the design of the northwest parking lot. It is fully compliant with the ToPV Zoning Ordinance and Building Code Analysis restrictions:
• Parking setbacks of 20 feet on streets
• Parking setbacks of 60 feet when adjacent to single family residential
Although we currently comply through interim remediation using T.O.P., completing the northwest parking lot work will greatly enhance our disability access and the safety of our parking lot. It also will upgrade our water and electrical service to meet current and future needs.
