• DETAILED DESCRIPTION OF WASTE Synthetic gypsum is generated as a by-product of flu&-gas desutfurisation (FGD) systems used to reduce GENERATING PROCESS sulphur dioxide emissions from coal-fired powerplants. Sulphur dioxide emissions from combustion

gases are removed using "scrubbers." One particular type of scrubber that uses lime or limestof'!e reagent and a forced oxidation system produces FGD gypsum, which is chemically nearly identical to mined natural gypsum and provides a wide-range of environmentally friendly applications.

Probability The probability rafara to the chance of impact to occur. The potential Impact could be most lkely to oa:ur, unlikely, etc.

Assessment of Signjficance of inpact

Significance rating of the potential impacts illustrates the inportanc:e of the impact ftself. l11e size of area affedad by poUution may be extremely high but the signific:anca of this effect is dependent on the concentration or level of pollution in that &IN. In order to determine the significance of impact, lhe following method was used:

Significance Poirrts (SP) = (Magnilude + Duration + Scale) x Probability

The values of SP are then ranged as follows: Rating Oesorfptll:m

SP>80 Indicates high environmental I An inpact which could influence the decision a~ significance whether or not to proceed with lhe activities

regardless of any possible mitigation.
