  1. Spanish Royal Decree for the statement of polluted soils Real Decreto 9/2005 (B.O.E nº15, 18 of January, 2005) The criteria to declare a site as polluted, as well as the possible restoration measures, are based on the potential unacceptable risks associated to the presence of contaminants. (Regulation (CE) nº 1488/94 and Regulation (CEE) nº 793/93). • Human Health • Environment JRC Meeting, 3-4 February, 2005

  2. Who has to present a declaration? • * The land owner of an potential polluting activity (Annex I). • * Those companies: • which produce, use or storage hazardous substances (> 10 tn/year) • average store of combustibles of 50.000 l and • average consumption of combustible > 300.000 l • Requested information: • General information about the activity • Hazardous substances used • Hazardous sub-products generated • Hazardous by-products generated • Storage • Existence of mechanisms/structures to preclude soil pollution • Historical uses/activities supported by the site JRC Meeting, 3-4 February, 2005

  3. TIERED SITE SPECIFIC RISK ASSESSMENT ? General approach (HH and Env) Concentration of contaminants in soil E(L)C50 / HIGH VALUES YES CONTAMINATED SOILS NO UNACEPTABLE POTENTIALLY CONTAMINATED SOILS ACEPTABLE NO GENREIC VALUES NON-CONTAMINATED SOILS YES JRC Meeting, 3-4 February, 2005

  4. HH CRITERIA NON-CONTAMINATED SOILS • Risk Assessment: acceptable risks for the Human Health • Priority in Human Health protection: below the Generic values (I,R,AU) Identification and definition of: Exposure routes Characteristics of the most sensitive target individuals Maximum Tolerable Concentrations (MTC) carcinogenic substances: frequency 10-5 systemic substances: ratio: long-term exposure/MTC 0.05 pesticides 0.2 organochlorinated substances 0.05 PAHs 0.1 MAHs Soil Uses: Industrial (I) Residential (R) Any use (AU) JRC Meeting, 3-4 February, 2005

  5. ENV. CRITERIA NON-CONTAMINATED SOILS • Risk Assessment: acceptable risks for the Environment • Priority in Environmental protection: below the Generic values (EU approach) JRC Meeting, 3-4 February, 2005

  6. HH / ENV. CRITERIA CONTAMINATED SOILS • Risk Assessment: Unacceptable risks for HH and/or Env • Priority in HH protection: if soil concentration > 100 * Generic values (I,R,AU) • Priority in Environmental protection: If E(L)C50, for most sensitive organism, is lower than 10mg of sampled soil/g soil test If E(L)C50, for most sensitive organism, is lower than 10 mg of leacheate/l medium test JRC Meeting, 3-4 February, 2005

  7. When is required a risk assessment? If the concentration of hydrocarbons in soil is higher than 50 mg/L If concentrations of any substance in soil is higher than the Generic Values. Regulation (CE) nº 1488/94 and Regulation (CEE) nº 793/93. • Requirements for the Environmental Risk Assessment: • Description of the sources of pollution • Description of soil characteristics • Identification of the potential target receptors • Environmental exposure and routes of • Risk characterization • Analysis of uncertainties JRC Meeting, 3-4 February, 2005
