The Humber Estuary European Marine Site THE HUMBER ESTUARY EUROPEAN MARINE SITE comprising: Humber Estuary possible Special Area of Conservation Humber Flats, Marshes and Coast Special Protection Area & potential Special Protection Area Humber Flats, Marshes and Coast Ramsar Site & proposed Ramsar Site English Nature¶s advice given under Regulation 33(2) of the Conservation (Natural Habitats &c.) Regulations 1994 INTERIM ADVICE APRIL 2003 Interim advice issued April 2003 English Nature¶s advice for the Humber Estuary European marine site given under Regulation 33(2) of the Conservation (Natural Habitats &c.) Regulations 1994 Preface This document provides English Nature¶s advice to other relevant authorities as to (a) the conservation objectives and (b) any operations which may cause deterioration of natural habitats or the habitats of species, or disturbance of species for the Humber Estuary European marine site. This advice is being prepared to fulfil our obligations under Regulation 33(2) of the Conservation (Natural Habitats &c.) Regulations 1994. European sites include Special Areas of Conservation (designated under the Habitats Directive, which support certain natural habitats and species of European importance) and Special Protection Areas (classified under the Birds Directive which support significant numbers of internationally important wild birds). Ramsar sites support internationally important wetlands and wetland species (listed under the Convention on Wetlands of International Importance especially as Waterfowl Habitat). In accordance with DETR'si Planning Policy Guidance (PPG9) and the DETR statement Ramsar Sites in England (November 2000); Ramsar sites must be given the same consideration as European sites when considering plans and projects that may affect them. European marine sites are defined in the Conservation (Natural Habitats &c.) Regulations 1994 as any part of a European site covered (continuously or intermittently) by tidal waters or any part of the sea in or adjacent to Great Britain up to the seaward limit of territorial waters. The Humber Estuary European marine site comprises a possible Special Area of Conservation ± the Humber Estuary; a Special Protection Area and Ramsar site - Humber Flats, Marshes and Coast Phase 1 (classified in July 1994) and a potential Special Protection Area and proposed Ramsar site - Humber Flats, Marshes and Coast Phase 2 (yet to be classified). Although parts of these European sites have not yet been formally designated, it has been agreed by the relevant authorities that this Regulation 33 advice will be progressed for the pSAC, pSPA and pRamsar, as well as for the designated areas. Our advice within this document will cover the marine elements of all of these sites. This µRegulation 33 package¶ is structured to help relevant and competent authorities, who have responsibilities on and around the Humber, to implement the Habitats Directive, and to: · understand the international importance of the site, underlying physical processes and the ecological requirements of the habitats and species involved; · advise relevant authorities as to the conservation objectives for the site and operations which may cause deterioration and disturbance; · set the standards against which the condition of the site¶s interest features can be determined and undertake compliance monitoring to establish whether they are in favourable condition; and · develop, if deemed necessary, a management scheme to ensure that the features are maintained. In addition, the Regulation 33 package will provide a basis to inform on the scope and nature of µappropriate assessments¶ required in relation to plans and projects (Regulations 48 & 50 and by English Nature under Regulation 20). English Nature will also provide more detailed advice to competent and relevant authorities to assess the implications of any given plan or project under the Regulations, where appropriate, at the time a plan or project is being considered. The designations on the Humber Estuary are currently under review by English Nature. This Regulation 33 advice will be updated in the future to reflect any subsequent changes to the boundaries or the features of the Humber Estuary European marine site.

  • U DDBA Papers of the Barnards Family 1401-1945 of South Cave
    Hull History Centre: Papers of the Barnards Family of South Cave U DDBA Papers of the Barnards Family 1401-1945 of South Cave Historical background: The papers relate to the branch of the family headed by Leuyns Boldero Barnard who began building up a landed estate centred on South Cave in the mid-eighteenth century. His inherited ancestry can be traced back to William and Elizabeth Barnard in the late sixteenth century. Their son, William Barnard, became mayor of Hull and died in 1614. Of his seven sons, two of them also served time as mayor of Hull, including the sixth son, Henry Barnard (d.1661), through whose direct descendants Leuyns Boldero Barnard was eventually destined to succeed. Henry Barnard, married Frances Spurrier and together had a son and a daughter. His daughter, Frances, married William Thompson MP of Humbleton and his son, Edward Barnard, who lived at North Dalton, was recorder of Hull and Beverley from the early 1660s until 1686 when he died. He and his wife Margaret, who was also from the Thompson family, had at least seven children, the eldest of whom, Edward Barnard (d.1714), had five children some of whom died without issue and some had only female heirs. The second son, William Barnard (d.1718) married Mary Perrot, the daughter of a York alderman, but had no children. The third son, Henry Barnard (will at U DDBA/14/3), married Eleanor Lowther, but he also died, in 1769 at the age of 94, without issue. From the death of Henry Barnard in 1769 the family inheritance moved laterally.

  • Case Study on Co2 Transport Pipeline Network Design for Humber Region in the Uk
    CASE STUDY ON CO2 TRANSPORT PIPELINE NETWORK DESIGN FOR HUMBER REGION IN THE UK Tihomir Lazica, Eni Okoa,b and Meihong Wanga,b,* aProcess Systems Engineering Group, School of Engineering, Cranfield University, Bedfordshire, MK43 0AL, UK bSchool of Engineering, University of Hull, HU6 7RX, UK *Corresponding author. Tel.: +44 1482 466688. E-mail address: [email protected] ABSTRACT Reliable, safe and economic CO2 transport from CO2 capture points to long term storage/enhanced oil recovery (EOR) sites is critical for commercial deployment of carbon capture and storage (CCS) technology. Pipeline transportation of CO2 is considered most feasible. However, in CCS applications there is concern about associated impurities and huge volumes of high pressure CO2 transported over distances likely to be densely populated areas. On this basis, there is limited experience for design and economic assessment of CO2 pipeline. The Humber region in the UK is a likely site for building CO2 pipelines in the future due to large CO2 emissions in the region and its close access to depleted gas fields and saline aquifers beneath the North Sea. In this paper, various issues to be considered in CO2 pipeline design for CCS applications are discussed. Also, different techno- economic correlations for CO2 pipelines are assessed using the Humber region as case study. Levelized cost of CO2 pipelines calculated for the region range from 0.14 to 0.75 GBP per tonne of CO2. This is a preliminary study and is useful for obtaining quick techno-economic assessment of CO2

    5. Amphibians and reptiles Common toad Bufo bufo Key Sites: Saltfleetby - Theddlethorpe NNR (TF 470 910). Summary Status: • Wildlife and Countryside Act: Schedule 5, Section 9 (5). • Habitats Directive: not listed. • Berne Convention: not listed. • Red Data Book: not listed. • Breeding Status in the Humber: Breeding. • Widespread and common or abundant. Description The common toad Bufo bufo is a widespread amphibian found throughout Britain although this species is absent from Ireland. They are generally brown, grey or dirty green and have the ability to lighten or darken their skin depending on environmental conditions. Their skin is covered in warts which secrete a toxic substance when the toad is seriously threatened. Like most toad species the common toad has short stubby legs. It therefore moves in a series of short hops rather than the large leaps taken by the common frog (Beebee & Griffiths 2000). The common toad tends to avoid grazed pasture, improved grassland, arable fields, heathland and moorlands in favour of rough grassland, scrub and open woodland. Large permanent water bodies with a good cover of emergent and submerged vegetation are preferred. Unlike other British amphibian species, they are able to inhabit ponds, which support fish, due to the unpalatability of common toad tadpoles (Beebee & Griffiths 2000). Common toads feed primarily on ground dwelling arthropods such as ants (family Formicidae), beetles (order Coleoptera), spiders (order Araneae) and earwigs (order Dermaptera), although slower moving items such as earthworms (Class Oligochaeta), and gastropods such as slugs and snails are also taken (Gittins 1987 in Beebee & Griffiths 2000). Distribution within the Humber As in many kinds of species survey, the observed distribution of records will reflect differences in recording effort as well as the real distribution of a species.

  • Explosion at the Conoco Humber Refinery – 16Th April 2001
    SYMPOSIUM SERIES NO. 151 # 2006 Crown Copyright EXPLOSION AT THE CONOCO HUMBER REFINERY – 16TH APRIL 2001 Jonathan Carter, Peter Dawson and Robert Nixon Health and Safety Executive, Hazardous Installations Directorate # Crown Copyright 2006. This article is published with the permission of the Controller of HMSO and the Queen’s Printer for Scotland An explosion and fire occurred at the Conoco Humber Refinery on 16th April 2001, following the catastrophic failure of a 600 overhead pipe from a de-ethaniser column on the Saturate Gas Plant. Investigation revealed that the failure of the pipe was due to internal corrosion that had not been identified by the refinery pipework inspection regime. The paper describes the event and the emergency response. It also examines the immediate cause of the event, and how failures of the management of pipework inspection and management of change failed to prevent the accident occurring. The paper concludes with the lessons that can be learned from this event. THE REFINERY The Humber Refinery is located on the south bank of the estuary of the River Humber on the east coast of England, approximately 1.5 km north-west of the town of Immingham and 0.5 km east of the village of Killingholme. In 2001 Conoco Ltd owned the refinery. In August 2002 Conoco merged to form ConocoPhillips Ltd., the current owners of the refinery. The refinery was constructed between 1966 and 1969 and commissioned in 1970. The current capacity of the refinery is about 225,00 US barrels per day of crude oil, or about 11.4 million tonne per year.

    RIVER QUALITY SURVEY NATIONAL RIVERS AUTHORITY NORTHUMBRIA & YORKSHIRE REGION GQA ASSESSMENT 1994 PART 1 REA CH CLASSIFICA TION FRESHWATER RIVERS AND CANALS VERSION 1: AUGUST 1995 GQA ASSESSMENT 1994 \ NORTHUMBRIA & YORKSHIRE REGION To allow the development of a National method of evaluating water quality, the rivers in all the NRA regions of England and Wales have been divided into reaches, which are numbered using a coding system based on the hydrological reference for each river basin. Each classified reach then has a chemistry sample point assigned to it and these sample points are regularly monitored for Biochemical Oxygen Demand (BOD), Dissolved oxygen (DO) and Total Ammonia. The summary statistics calculated from the results of this sampling are sent to a National Centre where the GQA Grades are calculated. A National report is produced and each region can then produce more detailed reports on the quality of their own rivers. For Northumbria and Yorkshire Region, this Regional Report has been divided into two parts. PARTI: REACH CLASSIFICATION This report contains a listing of the river reaches within the region, with their start and finish grid reference, approximate length, and the 1990 and 1994 GQA class for each reach. The reference code of the chemistry sample point used to classify the reach is also included. A sample point may classify several reaches if there are no major discharges or tributaries dividing those reaches. The sample point used to classify a reach may change and the classification is therefore calculated using the summary statistics for each sample point that has been used over the past three years.
