  1. 20 th Meeting HELCOM Monitoring and Assessment Group (HELCOM MONAS 20-2014) 8-10 April 2014, Oslo, Norway Draft revised HELCOM Guidelines for Management of Dredged Material at Sea Doc. 7-2-Corr.1

  2. HELCOM requirements on disposal of dredged material • Convention on the Protection of the Marine Environment of the Baltic Sea Area, 1992 – Article 11: Ban of any dumping at sea, except dredge spoil duly permitted by the authorities – Annex V: Exemptions from the general prohibition of dumping of waste • HELCOM Guidelines for the Disposal of Dredged Material at sea – legally-binding obligation – sets procedure for issuing disposal permits – sets frequency and format of national reporting

  3. Current HELCOM List of substances Primary List Secondary List (action levels to be established) (based on existing priority lists) ALSO MANDATORY if indicated • Cadmium (Cd) • Other chlorobiphenyls • Chromium (Cr) • Organochlorine pesticides • Copper (Cu) • Organophosphorus pesticides • Lead (Pb) • TBT, TPhT and their degradation products • Mercury (Hg) • Other anti-fouling agents • Nickel (Ni) • Petroleum hydrocarbons • Zinc (Zn) • Dioxins/furans • PCB congeners (28, 52, 101, 118, 138, 153 and 180). •ΣPAH9 • Arsenic (As)

  4. OSPAR List of substances Primary List Secondary List (action levels to be established) (based on existing priority lists) • Cadmium (Cd) • Other chlorobiphenyls • Chromium (Cr) • Organochlorine pesticides • Copper (Cu) • Organophosphorus pesticides • Lead (Pb) • Other anti-fouling agents • Mercury (Hg) • Petroleum hydrocarbons • Nickel (Ni) • Dioxins/furans • Zinc (Zn) • PCB congeners •ΣPAH9 • Arsenic • TBT and its degradation products Determination is conditional

  5. London Convention Action List • Constitutes a crucial part of Annex 2 to the 1996 LC Protocol • Each Contracting Party shall develop a national Action List • Priority shall be given to toxic, persistent and bio-accumulative substances from anthropogenic sources e.g., – Cd, Hg, organohalogens, petroleum hydrocarbons and, – whenever relevant, As, Pb, Cu, Zn, Be, Cr, Ni and Va, organosilicon compounds, cyanides, fluorides and pesticides or their by-products other than organohalogens • May be possible to define national action levels • Shall specify an upper level and may also specify a lower level. • Application of the Action List will result in categorisation of waste into 3 groups

  6. Waste Framework Directive: references to dredging activities • Art. 2 Exclusions from the scope Sediments relocated inside surface waters shall be excluded from the scope of the WFD under the following conditions: 1. Dredging is done for one of the following purposes: – managing waters and waterways or – preventing floods or – mitigating the effects of floods and droughts or – land reclamation 2. It is proved that the sediments are non-hazardous. • (21) Disposal operations consisting of release to seas and oceans including sea bed insertion are also regulated by international conventions, in particular the London Convention

  7. Further clarification of the relationship between the existing national interpretations in the application of the Waste Framework Directive to dredged materials and the management framework shared in OSPAR region and described in this document Dredged material Categories related to Waste Framework Directive Dredged material classification (chemical management National interpretations and biological) (OSPAR/Helsinki Convention) (i) (ii) (iii) + (v) (iv) Hazardous Hazardous Hazardous Hazardous Sediments where H1 to H15 properties waste waste waste waste (Waste Framework Directive annex III) need to be checked for classification into hazardous Non Non or non-hazardous hazardous hazardous waste (a) waste (a) Confined deposit (at Non sea) or management Contaminated sediments hazardous techniques to reduce or (> AL2) waste (a) control impacts Non Slight contaminated More detailed hazardous sediments Exempted assessment is needed waste (>AL1 & <AL2) (Art.3.2) (b) or Non hazardous to determine its Exempted (a) not waste, sediments, suitability for deposit at (Art. 3.2) (b) water including: National sea legislation (c) legislation Clean sediments (Art. 24 & 25) (b) (<AL1) Deposit al sea and beneficial use

  8. Overarching principles 1. Dredged sediment is a resource that should be used for beneficial purposes as an alternative to disposal in the ocean, when it environmentally, technically and economically feasible to do so. 2. Selection of management options for dredged material should be guided by "a comparative risk assessment involving both dumping and the alternatives" to dumping. 3. Management actions for dredged material should "ensure , as far as practicable, that environmental disturbance and detriment are minimized and the benefits maximized "

  9. Draft Guidelines for management of dredged material at sea New glossary Is an overarching term describing a variety of handling methods of dredged material dredged materials including, inter alia: dumping (deliberate disposal), re- management use, beneficial use, re-location, placement and treatment. Any deposit into the maritime area of dredged materials, independently of deposit whether it is considered as “dumping” or “placement” any deliberate disposal at sea or into the seabed of dredged material; subject to a prior special permit issued by the appropriate national dumping authority in accordance with the provisions of Annex V of the 1992 Helsinki Convention (Article 2 (4ai), 11 (2)) placement of matter for a purpose other than the mere disposal thereof, placement provided that such placement is not contrary to the aims of the present Convention (Article 2 (4bii) of the 1992 Helsinki Convention) Deposit in a structure planned and designed to contain dredged material confined disposal and safely contain any released contaminants, preventing their re-entry into the aquatic environment.

Draft Guidelines for management of dredged material at sea New Action Lists Primary List Secondary List (action levels to be established) (based on existing priority lists) ALSO MANDATORY if indicated List of metals, metalloids and organic/organo- metallic compounds to be determined • Cadmium (Cd) • Other chlorobiphenyls • Chromium (Cr) • Organochlorine pesticides • Copper (Cu) • Organophosphorus pesticides • Lead (Pb) • Tri-phenyl tin (TPhT) compounds and their degradation products • Mercury (Hg) • Other anti-fouling agents • Nickel (Ni) • Petroleum hydrocarbons • Zinc (Zn) • Polychlorinated dibenzodioxins • Arsenic (As) (PCDDs)/polychlorinated dibenzofurans •ƩPCB congeners (28, 52, 101, 118, 138, (PCDFs) 153 and 180). • Phthalates (DEHP and optionally - •ΣPAH16 and/or ΣPAH9 as a subgroup of /DBP/BBP) ƩPAH16 • Tri-butyl tin (TBT) compounds and their degradation products
