Tongling Tianhai fluid control Co., Ltd  We have received your company's application for environmental protection acceptance of hydraulic control valve project completion of Tongling Tianhai fluid control Co., Ltd., and environmental protection acceptance monitoring report for completion of hydraulic control valve project of Tongling Tianhai fluid control Co., Ltd. On September 15, 2015, our bureau set up an acceptance team to conduct on-site inspection on environmental protection acceptance of the project. After study, we reply the acceptance opinions as follows:

1、 The project is located in the standardized workshop of small and medium-sized enterprise entrepreneurship Park in Tongling Economic and Technological Development Zone. It has purchased lathes, machine tools, product testing and other production equipment, and completed the production of 50000 sets of hydraulic control valves annually. The actual total investment of the project is 23 million yuan, of which the environmental protection investment is 193000 yuan, accounting for 0.841% of the total project investment.

The project has fulfilled the environmental impact assessment procedures. In November 2014, the construction unit entrusted Anhui Siwei Environmental Engineering Co., Ltd. to prepare the environmental impact report form of hydraulic control valve project of Tongling Tianhai fluid control Co., Ltd., and our Bureau approved the report form with No. 66 [2014] of Tongling Tianhai fluid control Co., Ltd. In May 2015, our Bureau approved the trial production of the project with Tonghuan Han [2015] No. 222 document. At present, the production capacity of the project has reached more than 75% of the design scale, and the supporting environmental protection facilities have been constructed  Synchronous operation.

2、 Implementation of environmental protection measures

（1） The waste water from pressure test is recycled and not discharged. After treatment, the micro domestic wastewater will be connected to the drainage network of the park.

（2） The shot blasting dust is discharged through a 15 meter chimney after being treated by bag filter.

（3） Temporary storage of hazardous wastes shall be built in the plant area according to the requirements and handed over to Tongling Zhengyuan Environmental Engineering Technology Co., Ltd. for disposal. The processed leftovers are returned to the original manufacturer.

（4） Sound insulation and noise reduction measures are taken for main noise sources.

3、 Operation effect of environmental protection facilities and impact of project construction on Environment

Tongling Tianhai fluid control Co., Ltd. completed environmental protection acceptance monitoring report of hydraulic control valve project (Tongling Tianhai fluid control Co., Ltd.) provided by Tongling environmental monitoring center station shows that:

（1） Waste water

The waste water from pressure test is recycled and not discharged.

（2） Noise

The measured noise monitoring values at the boundary of each factory meet the requirements of class 3 zone standard of "emission standard of environmental noise at boundary of industrial enterprises" (gb12348-2008).

（3） Waste gas

The monitoring value of unorganized waste gas of the project meets the limit value requirements of Table 2 of integrated emission standard of air pollutants (GB16297-1996), and the dust in the outlet of bag filter for shot blasting waste gas meets the limit value requirements of Table 2 of integrated emission standard of air pollutants (GB16297-1996).

（4） Solid waste

Waste engine oil, oily fabrics and gloves are hazardous wastes. The temporary storage of hazardous wastes shall be built in the plant area according to the specifications, and then delivered to qualified units for disposal. Scrap materials, unqualified products, flange, metal solid waste generated in the process of car inner hole shall be cleaned and collected in time, and sold as resources for recycling; metal dust collected by shot blasting shall be sold out after collection.

4、 Acceptance conclusion and subsequent requirements

During the implementation of the project, corresponding environmental protection measures have been implemented according to the requirements of EIA documents and approval. After passing the acceptance, the main project is approved to be put into production.

During the operation of the project, the following work should be done well:

（1） Further standardize the treatment of the total wastewater discharge outlet and set up signboards.

（2） In strict accordance with the relevant management system of hazardous waste, the temporary storage site of hazardous waste should be set up in a standardized way, and signs should be set up to improve the management and transfer account of hazardous waste.

5、 The Environmental Protection Bureau of the development zone is responsible for the environmental supervision during the operation period of the project.
