Active Sub-Slab Depressurization (SSD) Sample Clauses

Active Sub-Slab Depressurization (SSD). A generalized illustration of an active SSD system is shown on Figure 10. An active SSD system typically consists of a blower and sub-slab air intake piping system. The SSD system is operated continuously to create a slight vacuum beneath the concrete floor slab of the building. The induced vacuum beneath the building floor slab overcomes the lower pressure that is sometimes found inside buildings. Therefore, when the SSD system is in operation, soil gases generally cannot flow from beneath the floor slab into the building. Rather, at the location of any cracks on the floor, indoor air will be drawn from inside the building into the lower pressure zone beneath the floor slab, thereby mitigating the vapor intrusion process. An SSD system requires installation of a vent intake pipe in one or more central or other appropriately selected location(s) in the baserock layer beneath a concrete floor slab. As an alternative, a geocomposite drainage mat or other liner with lateral permeability can be installed beneath the building and used as the means for withdrawing air from beneath the entire floor area. The vent pipe or drainage mat is connected to a blower to continuously create ventilation and a slight vacuum beneath the floor slab. The vacuum level created beneath the floor must be at a level sufficient to overcome the anticipated vacuum level inside the building (see design guidance documents listed in Section 5.1.3.1). The air and soil gases withdrawn from beneath a building during SSD operation are exhausted to the atmosphere. The emissions from the SSD systems will be treated to remove VOCs to the extent required by the Bay Area Air Quality Management District (“BAAQMD”) based on the estimated VOC emission rate for each system.4 4 For an SSD system at a nearby residential property on a former GTE site in Mountain View, California, treatment of SSD emissions was not required by BAAQMD due to low TCE emission rates relative to BAAQMD standards (U.S. EPA, 2004).

  • Underground Storage Tanks Borrower shall not install or permit to be installed on the Property any underground storage tank.

  • HEATING, VENTILATING AND AIR CONDITIONING The Tenant will operate and regulate those portions of the heating, ventilating, and air conditioning equipment within and serving the Leased Premises so as to maintain such reasonable conditions of temperature and humidity within the Leased Premises as are determined by the Landlord and its Architect and engineers so that no direct or indirect appropriation of the heating, ventilating and air conditioning from the other portions of the Building occurs.

  • Sub-Contracting JHSS may subcontract for the performance hereof, provided, however, that (a) upon engagement of any such subcontractor, and at least annually thereafter, JHSS discloses to the Board the financial terms of such subcontract and a summary of the services provided to the Fund pursuant to such subcontract, and (b) JHSS shall be as fully responsible to the Fund for any acts or omissions of any such subcontractor as JHSS is for its own acts and omissions.

  • Heating, Ventilation and Air Conditioning Landlord shall furnish to the Premises heating, ventilation and air-conditioning (“HVAC”) in accordance with the Design Standards set forth in Exhibit D during Ordinary Business Hours. Landlord shall have access to all air-cooling, fan, ventilating and machine rooms and electrical closets and all other mechanical installations of Landlord (collectively, “Mechanical Installations”), and Tenant shall not construct partitions or other obstructions which may interfere with Landlord’s access thereto or the moving of Landlord’s equipment to and from the Mechanical Installations. No Tenant Party shall at any time enter the Mechanical Installations or tamper with, adjust, or otherwise affect such Mechanical Installations. Landlord shall not be responsible if the HVAC System fails to provide cooled or heated air, as the case may be, to the Premises in accordance with the Design Standards by reason of (i) any equipment installed by, for or on behalf of Tenant, which has an electrical load in excess of the average electrical load and human occupancy factors for the HVAC System as designed, or (ii) any rearrangement of partitioning or other Alterations made or performed by, for or on behalf of Tenant. Tenant shall install, if missing, blinds or shades on all windows, which blinds and shades shall be subject to Landlord’s approval, and shall keep operable windows in the Premises closed, and lower the blinds when necessary because of the sun’s position, whenever the HVAC System is in operation or as and when required by any Requirement.
