Price indications for 2017 Cross-State Air Pollution Rule emissions allowances shifted lower across the board to kick off the month of October.

CSAPR seasonal nitrogen oxide emissions for 2017 saw a bid-and-ask range of $300 to $375 during the week ended Oct. 6, down slightly from a spread of $300 to $380 the week before.

In May, CSAPR 2017 seasonal NOx price indications surged to top $700, as buyers began to hedge ozone season emissions at a time when allocations were cut by more than 40% for the year by the U.S. Environmental Protection Agency.

But following an overall mild summer in many regions of the country, lackluster buying interest has largely kept pressure on 2017 seasonal NOx allowance prices since early September.

CSAPR 2018 seasonal NOx allowances were unchanged in a bid-and-ask range of $175 to $275 during the week under review.

CSAPR 2017 annual NOx allowances dropped to a bid-and-offer spread of $1.50 to $3, from a prior level of $2.00 to $4.00 at the end of September.

During the week ended Oct. 6, CSAPR 2017 Group 1 sulfur dioxide allowances eased to a bid-and-ask range of 25 cents to $4, down from 50 cents to $5 previously. CSAPR 2017 Group 2 SO2 allowances were assessed in a bid-and-offer spread of 25 cents to $5, dropping back from a range of 50 cents to $6 in the prior week.
