To use Table 6, the project must be connected to a municipal or district steam system that does not allow the return of steam condensate.

Table 6. Compliant municipal steam systems

Steam system	Requirement
Steam condensate disposal	Cool municipally supplied steam condensate (no return) to drainage system with heat recovery system or reclaimed water
OR	OR
Reclaim and use steam condensate	100% recovery and reuse

AND/OR

Option 4. Outdoor Water Use (1–2 points)

PATH 1. NO IRRIGATION (2 POINTS)

Show that the landscape does not require a permanent irrigation system beyond a maximum two-year establishment period.

OR

PATH 2. EFFICIENT IRRIGATION (1–2 POINTS)

Reduce the project’s theoretical irrigation requirement (TIR) by at least 50% from the calculated baseline. Points are awarded according to Table 7.

Table 7. Points for reducing outdoor water use

Percentage reduction	Points
50%	1
100%	2

AND/OR

Option 5. Optimize Process Water Use (1–2 points)

PATH 1. LIMIT COOLING TOWER CYCLES (1–2 POINTS)

For cooling towers and evaporative condensers, conduct a one-time potable water analysis, measuring at least the five control parameters listed in Table 8.

Table 8. Maximum concentrations for parameters in condenser water

Parameter	Maximum level
Ca (as CaCO3)	600 ppm*
Total alkalinity	500 ppm
