The total construction of a sewage treatment plant with a capacity of 50 million gallons per day completed 2013 in Wichita, Kansas was $6.5 million. It was proposed that a similar treatment plant with a capacity of 80 million gallons per day be built in Los Angeles, California, for completion in 2020. For the additional information given below, perform an prder of magnitude estimate of the cost of the proposed plant using the following steps in order:

a) In the total construction cost for the Wichita, Kansas plant, there was an item of $0.5 million for site preparation which is not typical for similar plants
b) The variation of sizes of the refineries can be approximated by the cost capacity factor with m=0.6
c) The inflation rate is expected to be 5% per year from 2011 to 2021
d) The location index is 0.84 for Wichita, Kansas and 1.04 for Los Angeles. These indices are deemed to be appropriate for adjusting thee costs between these two cities
e) New air pollution equipment for the Los Angeles plant costs $0.7 million in 2020 (not required in the Wichita plant)
f) The contingency cost due to inclement weather delay will be reduced by the amount of 1% of total construction cost because of the favorable climate in Los Angeles (compared to Wichita)
