Practical aspects of compliance with the
Integrated Permit requirements based on the
example of District Waste Water Treatment Plant
of Lódz Conurbation

Background

• The integrated permit system was imposed in the
  European Union by way of Council Directive
  96/61/EC of 24 September 1996 concerning
  integrated pollution prevention and control
  (IPPC).
• Integrated Permit. it is an administrative
  decision granting authorisation to operate an
  installation subject to certain conditions that
  guarantee that the installation complies with the
  requirements established for all environmental
  elements and with the best available technique
  (BAT), which determines the types and volumes of
  the raw materials, energy and fuels to be used

Objectives and requirements of the Integrated
Permit System

• Considerable and systematic improvement of
  environment in the European Union
• Prevention and further reduction of the
  pollutant emissions into the environment
• Operation of the installations will the possibly
  lowest impact on the environment as a whole
• Continuous improvement of the techniques intended
  to prevent pollution
• Development, implementation and constant
  improvement of the environment management systems
  in the industrial plants
• New methods of cooperation with environment
  protection authorities

Integrated permits for LC DWWTP

• DWWTP waste dump -Lagoons treatment and
  recovery of non-hazardous and neutral waste
  (storage)
• validity 31.01.2005 30.01.2015 3 updates
• Sludge and Screenings Thermal Treatment Facility
  treatment of sludge and screenings (thermal
  treatment)
• validity 12.01.2010 11.01.2020 1 update
• STTF waste landfill treatment of fly ash and
  dusts removed from the flue gases (storage)
• validity 12.01.2010 11.01.2020

Monitoring of pollutant emissions and immissions
Every year, the DWWTP Laboratory carries out
about 3500 monitoring tests. Some of the
laboratory tests (air, noise) are carried out by
the external laboratories.

BAT examples at the DWWTP Site

• Sludge thermal treatment (fluidized bed
  incinerators, monitoring of the process)
• Energy recovery at the STTF (heat recovery from
  flue gases, recirculation of steam and
  condensate)
• High quality sealing system of the waste
  landfill(electronic sensor based monitoring)
• Reduction of secondary fly ash and dusts
  re-entrainment from flue gas treatment to a
  minimum (moisturizing and spraying)
• Replacement of biodegradable waste (screenings)
  storage with thermal treatment process
  (incineration)

New obligations imposed on the IPPC installation
operators

• Directive 2010/75/EU of the European Parliament
  and of the Council of 24 November 2010 on
  industrial emissions (integrated pollution
  prevention and control) (IED) lays down new rules
  and obligations for prevention of industrial
  pollution. The Directive provisions should be
  implemented by the national legislation by 7
  January 2013. The key provisions include the
  following
• The requirement to adjust of the IPPC
  installations to the IED provisions (by 7 January
  2014),
• Establishment of new categories of activities
  (including WWTP) which have to comply with the
  IED requirements (as of 7 July 2015 r.).
• New rules and obligations imposed by IED
• Requirements of BAT reference documents will be
  legally binding,
• Requirement to report soil and groundwater
  contamination levels, and to carry out the
  relevant monitoring,
• New emission level requirements (SO2, NOx, dusts)
  for large incineration plants.

11
Experience acquired during implementation of the
IPPC Permit requirements

• Compared to the sector permit system the
  obligations of the IPPC installation operators
  are strengthened.
• If you have a single integrated permit for a
  large plant any modification considered
  significant by an environment protection
  authority involves the necessity to submit an
  application for permit revision for the whole
  plant (what needs time and financial outlays).
• every 5 years the IPPC Permit is reviewed in
  order to check the compliance with legislation
  and BAT requirements.
