    .01 Stormwater Systems
    1. Stormwater Management
      1. All projects shall include a stormwater management plan that conforms to the most recent local stormwater management ordinance.  Projects at University Park located within the Fox Hollow Drainage Basin shall conform to the Fox Hollow Drainage Basin Stormwater Management Design Manual.
      2. Recommended Practices
        • The University promotes foremost the use of conservation design practices that preserve and use natural critical hydrologic areas, including, but not limited to, floodplains, wetlands, streams, minor drainageways, natural recharge areas, carbonate closed depressions and sinkholes.  It also promotes the use and application of sound science in our stormwater management practices and does not believe that any BMP or Low Impact Development (LID) method can be used anywhere, or that we can engineer replacements to complex natural hydrologic areas. Therefore, site designers shall make every effort to preserve these areas, and any disturbance is only permitted at the approval of OPP Engineering Services.
        • Adequate treatment must be accomplished prior to stormwater runoff being injected into an engineered infiltration BMP or areas where infiltrated runoff can rapidly bypass the soils and enter fractures or the groundwater. Water quality pretreatment facilities must be visible and accessible to provide a means to monitor their efficiency, and replace if necessary in case of failure.  Every effort should be made to insure that the quality of stormwater that is to be artificially recharged is of equal or better quality than the existing groundwater.  If sinkholes or rapid infiltration does occur, limited water quality impacts may occur if the water is of high quality.
        • Construction practices must be utilized so as to minimize the compaction of existing soils.  In addition, a) soil at grade should be managed and b) vegetative cover and organic amendments should be utilized to enhance the restoration of infiltration capacity of disturbed soils.
        • As a nationally recognized institution of higher learning, the University reserves the right to request comprehensive computations that defends a designs function above and beyond those required for regulatory approval in order to protect health, safety, and welfare.
        • The University’s recommended practices for land development activities at shall be based on a thorough understanding of the watershed, soils, geology, site density, existing conditions, and the local regulatory requirements.  Examples of recommended practices are available for the University Park Campus from Engineering Services.
      3. Supporting Documentation
        • All stormwater management final reports and plans shall be provided to Engineering Services.  In addition to the stormwater reports required by a municipality and/or PaDEP, the professional must fill out and submit the Penn State Stormwater Management Facility Summary Sheets, and the Penn State Green Roof Summary Sheets, if applicable. Final payment can be held until documentation is received.
        • Digital as-built surveys of all stormwater management facilities, including but not limited to, surface ponds, underground detention facilities, BMPs, and conveyance pipes will be provided to Engineering Services.
        • All stormwater BMPs need to be properly installed, operated, and maintained.  The professional shall provide the University with three (3) copies of all stormwater Operations and Maintenance Manuals.  Additionally, the engineer shall fill out the Penn State Stormwater Operations and Maintenance Summary Sheet, for each BMP.
      4. The use of porous (asphalt) pavement is prohibited at University Park Campus.  Porous pavement may be used at other campuses at the approval of Engineering Services.
      5. The use of structural stormwater best management practices that replace existing subsoils with inert materials or gravel are discouraged unless it can be documented that the remaining soils are stable and can renovate pollutants in the stormwater.  Stating general rules of thumb, such as there are 2ft of soil above restricting layers, are not acceptable for documentation.

Steam valves shall be steel laminated seat zero leakage triple offset butterfly valves.  All valves to have gear operators.  Steam valves shall be ANSI Class 150 for low pressure steam and ANSI Class 300 for high pressure steam.  Valves material and construction shall be approved by Engineering Services.  Cast iron valves shall not be used.  Acceptable manufacturers are Adams, Tricentric, Zwick and Vanessa.
        2. Condensate valves 2 inch and smaller shall be stainless steel ball valves; e.g., Apollo.  Larger valves shall be high performance butterfly valves; e.g., Jamesbury or Keystone.  Valves material and construction shall be approved by Engineering Services.  Cast iron valves shall not be used. 
        3. Compressed air valves shall be stainless steel ball valves.
    4. Tests of Steam Distribution Piping
      1. New steam distribution piping systems which connect to existing hot steam lines shall be tested as follows:
        1. The new system shall be installed and the ends of the lines blanked off prior to making the connection to the existing hot line.
        2. The line shall then be hydrostatically tested as specified and thoroughly flushed out.
        3. Make final connections to existing hot lines, energize, and waste condensate.
        4. De-energize and open and clean all dirt legs and strainers.
          • (The purpose of this test is twofold:  (1) To stress line under expanded conditions prior to hydro test; and (2) To knock off and then flush out as much mill scale and debris as possible.)
    .02 Air
    1. Characteristics
      1. Line pressure 60-80 pounds.  This is central plant air and is available on most of the University Park Campus.  Provide proper dryer and separator tanks with automatic blowdown piped to nearest drain, and provide refrigerated air dryer with automatic blowdown piped to nearest drain.
      2. Oil removal equipment must be provided in the building.
      3. Central air is not available at other locations.
    2. Distribution Systems
      1. Underground compressed air piping shall be fiberglass reinforced plastic (Fibercast, Centricast Plus RB-2530).  Where piping passes through manholes, convert to steel with flanges.
      2. Piping shall have a trap, with a half-inch ss ball valve and an automatic drain located at the low point where the piping enters the building.  In addition, half-inch ss ball valves with brass plugs shall be provided at all low points to bleed entrapped moisture.  Provide oil filters in the lines as needed.
      3. All underground fiberglass piping shall have a twelve gauge stranded copper tracer wire attached to the top of the pipe.
    3. System Tests
      1. All air lines shall be tested at 100 psi air pressure for a period of four (4) hours using test connections and testing equipment furnished by the Contractor.  The only permissible drop in pressure shall be that due to temperature drop.
