e e 24. Tangent Pier vs. Sheetpile Construction . The standard construction technique at water's edge involves sheetpiles that are driven into the earth. The applicant will use the Tangent Pier construction technique for the 7,000 foot container wharf. This will reduce both water quality and noise impacts. 25. North Shore Noise Wall A twenty-foot pre-cast concrete wall has been designed to -mitigate the potential noise impacts to the North Shore Communities (Figures 28 & 29). Additionally, there will be enhancement planting to ensure at least three trees every 20 linear feet on the North side of the wall. Loblolly Pines will be planted where needed (Figure 29). 26. Spreader Bars To further reduce the potential noise impacts to the North Shore communities, the PHA will installing impact noise reductions system on all wharf crane spreader bars utilized at Bayport. Air Initiatives 27. General Conformity - The applicant will reduce general conformity related emissions below the 25-ton per year de minimus threshold to decrease air emissions during construction. Contractors will bid on varying construction scenarios based on emission calculations and the 25-ton threshold. Bidders will be required to use a ''NOx calculator" developed by the applicant that will consider TCEQ approved technologies such as Tier n engines and the use of PuriNOx fuel in emissions calculations. . 28. Texas Emission Reduction Program. (TRRP) - Contractors are requested in construction contracts to make an attempt to secure grants and other incentives associated with TRRP under . Senate Bill 5. 29. On-road Diesel Grade Fuel- Port operations will include the use of on-road diesel grade fuel in all off-road equipment instead of higher sulfur content off-road diesel. This ensures that equipment emissions are kept to a minimum. 30. Equioment Maintenance - Regular maintenance checks on all equipment ensures that emissions remain at levels recommended by equipment manufacturers. Procedures will include an automatic printout for equipment in need of regular maintenance. Recommended tire pressures will be maintained in all equipment ensuring maximum fuel economy and thus reduced emissions. An aggressive engine overhaul program will minimize effects of engine degradation and prevent increased emissions. 31. Eauioment Operation - Whenever possible, equipment will be refueled during evening hours when temperatures are cooler to minimize evaporation and fugitive emissions. The applicant will encourage the use of off-road equipment later in the day to decrease ozone impacts where feasible and practical. Port of Houston Authority No. 21520(Revised) .
