Annual Report 2012

Environment

Acron Group recognises its socil responsibility to protect the environment, contribute to safe living conditions near its facilities and use natural resources wisely. The Group’s sustainable growth is conditioned on its long-term programme for environmental protection and safe operations.

The Group’s environmental policy is founded on the following principles:

  • Ensuring compliance with environmental laws.
  • Monitoring wastewater quality and quantity, air emissions and the operation and conditions of waste storage facilities.
  • Elaborating and enforcing limits on waste emissions, discharge, and storage.
  • Monitoring environmental conditions within the sanitary protection zone surrounding facilities, neighbouring populated areas and water bodies.
  • Introducing measures to reduce discharge, polluting emissions and waste generation and to ensure environmentally safe waste storage and disposal.
  • Using natural resources wisely.
  • Introducing new cutting-edge equipment and technologies to mitigate the impact of industrial waste on the environment.

Environmental measures in 2012

Key measures to decrease discharge of pollutants into water bodies

  • Acron (Veliky Novgorod) enacted a set of measures to ensure stable and accident-free operation of its biological treatment plant (Stage 1 and 2), installed wastewater sampling platforms at the sewage treatment canal for the water supply and sewerage plant; decreased wastewater discharge into the wastewater drain, purchased ammonia gas condensers; and completed renovation of drainage gutters and the concrete surface between railway tracks No. 41 and 42 at the ammonium nitrate plant.
  • Dorogobuzh installed an ultraviolet wastewater decontamination plant that prevents the disinfectant (chlorine) from ingressing into surface water bodies and achieving a higher efficiency of wastewater decontamination; the Company also completed major repairs of the primary sedimentation tank at its biological treatment plants and conducted pre-plan analysis of drainage water with the goal of eliminating heavy metals.
  • Hongri Acron completed its wastewater reuse system.

Key measures to decrease atmospheric emissions

  • Acron (Veliky Novgorod) replaced the waste gas heat booster of Unit 2 and catalysts ABK-10M in the catalytic refining reactor in the nitric acid shop; replaced the washing scrubber filter cloth of Unit 2 and repaired the washing scrubber demisters of Unit 1 in the ammonium nitrate shop; replaced the bag filters and nozzle for the gas dusting equipment at NPK units 1, 2 and 3.
  • Dorogobuzh carried out selective replacement of filtering elements in bag filters; the filter cloth in the scrubbers filters were replaced in Units 1 and 2 of the ammonium nitrate shop; an AHKAT-410-01 gas analyser was put into operation at Unit 3 in the weak nitric acid shop; filtering elements of bag filters and scrubber fabric were replaced in the fertiliser shipping shop; in the ammonium shop the emission was transferred from oil collectors of compressor 103-j to suction compressor 102-j.
  • Hongri Acron completed a dust-collecting system improvement project at its NPK production unit.

Key measures to reduce waste generation, to store and dispose the waste

  • Acron (Veliky Novgorod) carried out ecological monitoring of land plots owned by Trubichino and used for sludge storage at the biological treatment plant and disposed of biological treatment plant sludge from temporary storage sites.
  • Dorogobuzh is pursuing construction of a new site for centralised collection of hazard categories 2-5 waste. The Company carried out rehabilitation of Sector 7 of the industrial waste dump and extended the calcium carbonate storage facility dam (Stage 2).
  • Hongri Acron commenced construction of a 400-ktpa phosphogypsum complex recycling system, which will reduce the total amount of solid waste by 45%.

Accidents, emissions and spillage

No emission or spillage-related accidents were recorded at the Acron, Dorogobuzh and NWPC production sites in 2012. Hongri Acron recorded one accident related to a minor outflow of ammonia at the production site.

The Group’s commitment to environmental protection

Under Russian and Chinese laws, the Group’s facilities are subject to pay- to-pollute charges, which include air emissions, wastewater discharge and solid waste disposal. In 2012, Acron (Veliky Novgorod) paid RUB 3.1 million in environmental impact charges, Dorogobuzh paid RUB 11 million, NWPC paid RUB 5.9 million and Hongri Acron paid RUB 2.8 million to offset environmental impact.

Key environmental protection steps at the Oleniy Ruchey mine construction site in 2012

  • Implementation of an environmental monitoring programme for surface and underground waters and atmospheric air condition in the licence area of the permit and local radiation monitoring.
  • Construction of water protection installations at the area affected by the mine site: waste water treatment facilities with biological treatment and reverse osmosis tertiary treatment systems, storm water treatment plants, tailing unit with a final setting tank to prevent the ingress of pollutants into water bodies.
  • Completion of the first stage of the biological and geological barrier to suppress dust on the road slopes and construction of an avalanche- proof dam.
  • Ensuring timely waste collection for disposal, treatment and/or recycling, organising in-process control of waste treatment, marking of waste storage sites. A set of measures has been developed to reduce waste generation, ensure waste disposal and comply with applicable waste treatment requirements and regulations.

The Federal Agency for Fisheries recommended that NWPC build a fish farm for whitefish and salmon reproduction as a compensatory measure to offset the impact on biological resources in the Kuna and Partomyok rivers and Umbozero Lake resulting from the Oleniy Ruchey mine construction. NWPC signed an agreement to design a fish farm and conduct a preliminary full-scale fishery inspection of the Komarinoye and Umbozero Lakes.
