Maximum permissible emissions project (PDV)
Inventory of emission sources, atmospheric dispersion modelling and justification of emission limits to obtain a permit.
Professional PDV project development (Maximum Permissible Emissions project for atmospheric air protection) and comprehensive regulatory environmental consulting are core specialized engineering services provided by GEO PRO. High-quality and timely PDV project development in Tashkent, the Tashkent Region, and across the Republic of Uzbekistan guarantees operating and newly designed industrial facilities full compliance with national environmental legislation and ensures the prompt receipt of an official positive conclusion from the State Ecological Expertise along with the statutory atmospheric emission permit.
According to statutory environmental protection standards, official PDV project development is legally mandatory for any enterprise whose industrial, heating, auxiliary, or transport operations involve the release of hazardous pollutants into the atmosphere. The PDV documentation establishes scientifically grounded emission limits for each stationary source and specific chemical substance, accounting for regional background air pollution. The primary objective is to guarantee that ground-level pollutant concentrations at the boundary of the sanitary protection zone (SPZ) and in adjacent residential areas do not exceed maximum permissible concentrations (MPC / hygienic standards). Operating manufacturing facilities without an approved PDV project volume leads to severe administrative penalties, mandatory suspension directives, and multiplied environmental compensation levies.
Legislative Framework and Objectives of PDV Project Development
In accordance with the Laws of the Republic of Uzbekistan “On Atmospheric Air Protection”, “On Nature Protection”, and Cabinet of Ministers Resolution No. 541, all legal entities and industrial polluters are legally obligated to maintain an accurate inventory of emission sources and establish regulatory limits.
Environmental engineers at GEO PRO draft technical project files in rigorous compliance with the regulatory guidelines of the Ministry of Ecology, Environmental Protection and Climate Change of the Republic of Uzbekistan, ShNK construction codes, and SanPiN sanitary norms. Our accredited geotechnical and environmental chemical testing laboratory utilizes calibrated gas analyzers and sampling probes to perform direct instrumental measurements of dust, flue gases, and heavy metals at smokestacks, ventilation outlets, and technological ducts.
Scope of Engineering Services in PDV Project Documentation
During the preparation of the comprehensive project volume, our environmental team carries out a complete cycle of analytical, instrumental, and calculation tasks:
- Emission source inventory: Comprehensive identification, numbering, and spatial mapping of all organized (stacks, roof fans, air ducts) and unorganized (open stockpiles, material transfer points, raw material heaps) emission sources;
- Instrumental measurements and laboratory analysis: Determining physical parameters of gas-air mixtures (flow rate, velocity, temperature) and chemical analysis of pollutant concentrations;
- Atmospheric dispersion modelling: Advanced mathematical computer modeling of ground-level air concentrations using certified unified air pollution calculation software, incorporating local wind roses and background meteorological data;
- Justification of emission limits and action plans: Calculating maximum one-time emission rates (g/s) and annual gross emission volumes (tons/year) for each specific pollutant;
- Action plan for adverse meteorological conditions (NMU): Formulating operational protocols for short-term emission reductions during severe smog or stagnant weather events;
- Industrial Environmental Control Program (IECP): Establishing an internal enterprise monitoring schedule and emission source verification protocols.
Which Industrial Sectors Require a PDV Project
Executing professional PDV project development and obtaining official emission permits is mandatory across diverse economic sectors:
- Heavy industry and metallurgy: Smelting workshops, foundries, mechanical processing plants, welding units, and industrial coating chambers;
- Building materials manufacturing: Cement factories, brickworks, lime plants, dry mix facilities, and asphalt concrete mixing installations;
- Energy and thermal power complexes: Thermal power plants (TPP), industrial steam and heating boilers operating on gas, coal, or fuel oil, and heavy diesel generator units;
- Chemical and petrochemical plants: Refineries, bulk petroleum depots, paint and polymer production facilities, and chemical synthesis plants;
- Agro-industrial and food processing: Grain drying complexes, elevators, feed mills, poultry plants, and vegetable oil extraction facilities.
Approval Procedure in the State Ecological Expertise
GEO PRO delivers turnkey management throughout the entire government review and approval cycle:
- Engineering site visits to evaluate technological flowcharts, fuel consumption data, and gas-cleaning unit (GCU) passports;
- Conducting instrumental sampling and certified laboratory testing of flue gases;
- Executing dispersion calculations, drafting explanatory notes, and preparing technical map annexes;
- Submitting the completed project package to SUE “Center of State Ecological Expertise” via the official digital portal;
- Technical defense of all calculation models before the state expert commission and obtaining the final approved conclusion valid for up to 5 years.
Cost and Timeline for PDV Project Development in Tashkent
The cost of PDV project development is determined individually based on the total number of emission points, the variety of chemical substances emitted, and the operational complexity of the site. Leveraging our accredited in-house laboratory and seasoned environmental engineers, we provide accurate project documentation without middlemen at competitive rates.
