For the other owner costs a factor of 1.75 was used for everything except the SCR to represent balance of plant cost, electrical costs, AFUDC etc.For the SCR a factor of 1.25 was used because the material cost of $250/kW from the CH2M HILL database already included the balance of plant and a few other costs
