Dis­posal of frack­ing waste wa­ter gets ap­proval

Cape Breton Post - - PROVINCIAL -

The Nova Sco­tia gov­ern­ment has given a com­pany ap­proval to dis­pose of more hy­draulic frac­tur­ing waste wa­ter that is stored in two hold­ing ponds near Ken­net­cook.

The waste wa­ter will be used as a coolant in a kiln at the La­farge ce­ment plant in Brook­field and evap­o­rated at 700 de­grees Cel­sius af­ter be­ing treated for nat­u­rally oc­cur­ring ra­dioac­tive ma­te­ri­als with a process called re­verse os­mo­sis.

The gov­ern­ment has said that a pre­vi­ous pi­lot pro­ject of two mil­lion litres showed eva­po­ra­tion is a vi­able dis­posal so­lu­tion for the waste wa­ter.

Last Oc­to­ber, the province al­lowed At­lantic In­dus­trial Ser­vices to treat an ad­di­tional five mil­lion litres of waste wa­ter left over from drilling in 2007 and 2008.

The work is ex­pected to be­gin next week and will see the com­pany re­lo­cate its wa­ter treat­ment equip­ment from Debert to Ken­net­cook, with up to eight truck­loads of treated wa­ter trans­ported daily to the ce­ment plant.

The province says Tri­an­gle Petroleum has 20 mil­lion litres of waste­water in the two hold­ing ponds in Ken­net­cook.

“This is a sig­nif­i­cant mile­stone and good news for Ken­net­cook res­i­dents who have been look­ing for­ward to dis­posal since the eva­po­ra­tion pi­lot proved to be a vi­able so­lu­tion for ad­dress­ing the province’s hy­draulic frac­tur­ing waste wa­ter last year,” En­vi­ron­ment Min­is­ter Randy Delorey said in a state­ment.
