Data re­views are the sys­tem’s back­bone

China Daily (USA) - - CHINA - By ZHENG JIN­RAN

Zhao Cheny­ing is an in­spec­tor for the Bei­jing Mu­nic­i­pal En­vi­ron­men­tal Mon­i­tor­ing Team. It’s a de­mand­ing job, be­cause the com­pa­nies he deals with cover a wide range of sec­tors, from restau­rants to chem­i­cal com­pa­nies to power plants, which re­quires Zhao to un­der­stand tech­ni­cal­i­ties in a num­ber of fields.

On July 21, Zhao re­viewed the va­lid­ity of emis­sions data pro­vided by theHua­dian Ther­mal Power Plant in Bei­jing, a branch of Chi­naHua­dian Corp.

He in­spected the en­tire process, start­ing by col­lect­ing and mea­sur­ing pol­lu­tants in the 100me­ter-high chim­ney, where he mea­sured the emis­sions data with por­ta­ble equip­ment be­fore com­par­ing the re­sults with those sup­plied by the com­pany.

Sim­i­lar cross­checks are ap­plied to fol­low-up pro­cesses, in­clud­ing check­ing data read­ings from both the host ma­chines and the boxes that up­load the data to the mu­nic­i­pal plat­form on pol­lu­tant emis­sions.

“If the two groups show large dis­crep­an­cies in any of the pro­cesses, the com­pany will be re­quired to re­view and fix the fa­cil­i­ties to guar­an­tee data va­lid­ity,” Zhao said.

The com­pa­nies have grad­u­ally re­al­ized the im­por­tance of auto-mon­i­tor­ing fa­cil­i­ties ... ”

Cross­check­ing isa­nun­com­fort­able job be­cause most of the fa­cil­i­ties in­stalled near pol­lu­tant­dis­charg­ing out­lets are sit­u­ated in high, wet or noisy po­si­tions, such as the host­ma­chine­in­stalled near the ther­mal plant’s steam boiler, where the tem­per­a­ture was around 50 C.

Inad­di­tion to quar­terly re­views of data va­lid­ity, Zhao and his col­leagues are re­spon­si­ble for monthly inspections at busi­nesses known to be large emit­ters, such as Hua­dian, while other com­pa­nies are sub­ject to ran­dom mon­i­tor­ing.

There are about 500 in­spec­tors for the cap­i­tal’s down­town and sub­ur­ban dis­tricts, but there are more than 10,000 pol­lu­tant-dis­charg­ing com­pa­nies. “It’s im­pos­si­ble to in­spect them all fre­quently,” said Li Bin, Zhang’s col­league.

Bei­jing’s emis­sions-mon­i­tor­ing plat­form, which be­came op­er­a­tional in 2012, cov­ers 172 ma­jor com­pa­nies with high lev­els of emis­sions, sup­ple­ment­ing the work of field in­spec­tors, Li said.

The plat­form al­lows in­spec­tors im­me­di­ate ac­cess to hourly emis­sions data, he added.

In the past two years, only 12 com­pa­nies have been ex­posed as hav­ing ex­ces­sive lev­els of emis­sions or fail­ing to in­stall mon­i­tor­ing fa­cil­i­ties in ac­cor­dance with their own sched­ules.

“The com­pa­nies have grad­u­ally re­al­ized the im­por­tance of au­tomon­i­tor­ing fa­cil­i­ties, which pro­vide a good way of prov­ing their per­for­mance in re­duc­ing pol­lu­tion,” Li said, adding that strict con­trols mean com­pa­nies must be­come en­vi­ron­men­tally friendly if they want to con­tinue op­er­at­ing in the cap­i­tal.

In the first months of op­er­a­tion, when an alert was sounded the in­spec­tors had to call com­pa­nies to dis­cover the rea­son, but now, com­pa­nies vol­un­tar­ily no­tify the in­spec­tors of the causes of ab­nor­mal read­ings and the mea­sures they will take to rec­tify the prob­lem, Li said.
