Solids Handling And Storage

  1. 1. Solids handling and storage How do we protect the surface water? Mr. Paul Bakker
  2. 2. Introduction <ul><li>Directorate for Public Works and Water Management (Rijkswaterstaat = RWS) </li></ul><ul><li>Part of the Ministry of transport, public works and water management </li></ul><ul><li>10 Regional directorates, South Holland </li></ul><ul><li>Department Authorization of South Holland </li></ul><ul><li>- 106 IPPC-companies emitting towards surface water </li></ul><ul><li>- around 800 companies in total emitting towards surface water </li></ul>
  3. 3. Water Policy in the Netherlands <ul><li>Dutch legislation: Waterwet: Surface Waters Pollution Act (2009) </li></ul><ul><ul><li>No discharge allowed without a permit (general rule) </li></ul></ul><ul><ul><li>You request for permission to discharge wastewater.(permit) </li></ul></ul><ul><ul><ul><ul><ul><li>Refineries </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Chemical industries </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Energy sector </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>Waste processors </li></ul></ul></ul></ul></ul><ul><ul><ul><ul><ul><li>And so on. </li></ul></ul></ul></ul></ul>
  4. 4. General Emission Immission Approach <ul><li>General approach: gather information </li></ul><ul><li>about the quality of the discharge </li></ul><ul><li>The assessment of the factory and the sewage system with regard to the Best Available Techniques (BAT) </li></ul><ul><ul><li>BAT is described in the IPPC-documentation. </li></ul></ul><ul><li>The assessment of the residual emissions with the Immission Test. </li></ul><ul><li>Permit with regulations. </li></ul>Water Policy + BAT residual emissions
  5. 5. How is this reflected to EMO? <ul><ul><li>Emo is no IPPC company. </li></ul></ul><ul><ul><li>There is still the obligation to have a permit </li></ul></ul><ul><ul><ul><ul><ul><li>Exception </li></ul></ul></ul></ul></ul><ul><ul><li>General environmental rules (AMvB Guidelines). </li></ul></ul>
  6. 6. AMvB Guidelines <ul><li>General guidelines for a group of companies with the same discharges to the environment or a specific sort of wastewater discharge. </li></ul><ul><li>Examples for the discharge of wastewater are: </li></ul><ul><ul><li>Handling and storage of solids. </li></ul></ul><ul><ul><li>Domestic wastewater </li></ul></ul><ul><ul><li>Rainwater </li></ul></ul><ul><ul><li>Small heat discharges from cooling systems </li></ul></ul>
  7. 7. Why general guidelines? <ul><li>About 130 companies in the Netherlands for which the handling and storage of solids is the core business. </li></ul><ul><li>Environmental discharges and impact More or less the same </li></ul>
  8. 8. AMvB <ul><li>To regulate a group with the same wastewater discharges we need requirements with give the room to operate a business but also protect the environment. </li></ul><ul><li>Therefore the AMvB consists of 2 types of regulations: </li></ul><ul><ul><li>Discharge requirements for the wastewater. </li></ul></ul><ul><ul><li>Good-housekeeping. </li></ul></ul><ul><ul><li> </li></ul></ul>
  9. 9. AMvB Discharge requirements <ul><li>Example of the wastewater discharge for the H&S sector. </li></ul>1 - 8 mg/l 1,5 mg/l 10 mg/l Total N < 1mg/l < 0,1 mg/l 1 mg/l Metals 20 - 200 mg/l 125 mg/l 200 mg/l COD 10 - 200 mg/l 15 mg/l 50 mg/l TSS Average discharge H&S Discharge EMO AMvB regulations Parameter
  10. 10. Good housekeeping 1 <ul><li>Two examples of good housekeeping: </li></ul><ul><li>The distance between the ship and the wharf has to be as small as possible to prevent diffuse discharges. </li></ul>
  11. 11. Good housekeeping 2 Bufferpond 20.000 m3 20% 10.000 m3 80%
  12. 12. The difference between a permit and general rules. <ul><li>Permit </li></ul><ul><li>No discharge without a permit. </li></ul><ul><ul><li>No unless </li></ul></ul><ul><li>Getting a permit takes 6 months. </li></ul><ul><ul><li>Extensive citizen participation </li></ul></ul><ul><li>Difference between companies </li></ul><ul><li>BAT is a part of the considerations in the permit. </li></ul><ul><li>Immediate control </li></ul><ul><li>General rules </li></ul><ul><li>Discharge accepted unless the consequences are to great. </li></ul><ul><ul><li>Yes unless </li></ul></ul><ul><li>After notifying you have permission. </li></ul><ul><ul><li>No participation for citizens </li></ul></ul><ul><li>Everyone has the same guidelines </li></ul><ul><li>BAT is included in the general guidelines. </li></ul>
  13. 13. Conclusion <ul><li>Why should we do it? </li></ul><ul><li>Less bureaucratise than a normal permit. </li></ul><ul><li>Uniform guidelines. </li></ul><ul><li>BAT is defined, no discussion. </li></ul><ul><li>Potential risk. </li></ul><ul><li>No immediate control. </li></ul><ul><li>Less local considerations. </li></ul><ul><li>No citizen participation. </li></ul>
