POTTSTOWN » The pub­lic has un­til Aug. 8 to com­ment on a plan to con­trol stormwa­ter for the next five years.

The plan is re­quired to ob­tain a per­mit from the Penn­syl­va­nia De­part­ment of En­vi­ron­men­tal Pro­tec­tion as part of the mu­nic­i­pal sep­a­rate storm water sys­tem, a re­quire­ment of the fed­eral Clean Water Act.

Tom Weld, en­gi­neer for the Pottstown Bor­ough Au­thor­ity, which has ac­cepted re­spon­si­bil­ity for man­ag­ing the bor­ough’s storm water, pre­sented the plan to bor­ough coun­cil July 5.

In ad­di­tion to con­tin­u­ing to mon­i­tor for po­ten­tial PCB chem­i­cal con­tam­i­na­tion from sev­eral old in­dus­trial sites, the bor­ough must re­duce by 10 per­cent the sed­i­ment car­ried by Goose Run, a trib­u­tary of Manatawny Creek that be­gins in Up­per Potts­grove and runs through High­land Memo­rial Park ceme­tery be­fore head­ing un­der­ground into the storm sewer sys­tem.

That means the bor­ough needs to re­move 52,197 pounds of sed­i­ment from Goose Run each year.

That will be ac­com­plished, Weld said, with the in­stal­la­tion of two sed­i­ment traps, one near Airy Street east of North Hanover Street, and one near Fourth Street, west of North Hanover Street.

Ad­di­tion­ally, an “in­fil­tra­tion trench” will be in­stalled at the Airy Street site.

All to­tal, the project is ex­pected to cost about $200,000.

Weld said the bor­ough al­ready has a $40,000 grant to pay for the sed­i­ment trap at Fourth Street, and his firm has iden­ti­fied an­other $100,000 in grants for which the project may be el­i­gi­ble.
