Talk:River Afan

message: Has the Afan Valley Angling Club changed its name to Afan Valley Angling Association? If not, I'll edit the article.

message: This section refers to the pollution of the Pelena.  It says it was caused by: "The principal collieries responsible were those located in Glyncorrwg and Aber/Blaengwynfi...".  This doesn't make geographical sense in relation to the Pelena (check on a map) and is clearly wrong.  It may be a reference to pollution of the river Afan, but it is in the wrong place.  Unless it is amended or someone else has any relevant comments I will remove it. Huwbwici (talk) 11:41, 23 April 2009 (UTC)
replies: text: You are right . This is a product of an anonymous editor in August 2007 who changed my original correct answer to a totally wrong answer (as you note). Now corrected again.  Velela  Velela Talk   17:33, 23 April 2009 (UTC)
thread_title: Afon Pelena - polluting collieries

message: My memory and all references refer to PELENNA with two N's, not PELENA with one.  I don't think they are Welsh and English versions, I think there is just one version with 2 N's.  Does anyone know any different?  Otherwise, this should be changed. Huwbwici (talk) 11:45, 23 April 2009 (UTC)
replies: text: Unfortunately this IS one of those English/ Welsh variants - although we had got it wrong in the article (now corrected). The Ordnance Survey uses River Pelena and Afon Pelenna. As this is the English Wikipedia I guess we should standardise on River Pelena as it is commonly called that along the Afan valley and in Port Talbot.  Velela  Velela Talk   17:29, 23 April 2009 (UTC)
thread_title: Afon Pelena

message: "This water too was grossly polluted for many years, principally with cyanide emanating from blast-furnace cooling waters. This had the very visible impact of killing thousands of smolts—the young of sea-trout—returning to the sea. With recent improvements in emission control in the steel making plant, this problem has been abated."
This uncited statement,I believe is rubbish. It talks about Blast Furnace cooling waters polluting the river with cyanide , but then goes on to talk about emission improvements at the steel plant.
What evidence is there that smolts were killed by cyanide anyway. I believe this part of the paragraph should be deleted.

replies: text: I agree that it is probably difficult to find good references for this but I can attest to the truth of the statement as probably can many surviving members of the Afan Angling Association who helped with the smolt surveys that were undertaken  and in monitoring the regretfully many smolt kills. The connection between cyanide and emissions control is very simple. Prior to good emissions control practices blast furnace gas quenching waters were released straight back into Port Talbot docks through which ran the Ffrwdwyllt. These waters contain ammonia, cyanide and many other products of combustion and coal carbonisation. With improved controls these waters were re-directed to water treatment facilities and not discharged to the environment. For the record, I was a senior environmental scientist with Welsh Water who were, at the time, the environmental regulators for rivers in Wales. It concerns me that you have formed a view that this rubbish  when there is plenty of evidence of the impacts of blast-furnace waters and their potential, to pollute, the presence of the blast-furnaces near the Ffrwdwyllt is not in doubt, British Steel (the then operators) never denied that they made the releases (which were not illegal at the time because of a quirk in the law) yet you have formed a contrary view. It concerns me that there is sometimes a wish to white-wash the past, but white-washing doesn't make it more true.  Velella  Velella Talk   20:41, 3 May 2011 (UTC)

text: Thank you for your possibly very valid comments, however a Steel Plant, as stated in the article, is not a Blast Furnace which produces iron. I fail to see how the Steel Plant at Port Talbot has anything to do with the waters of the river Ffrwdwyllt, anyway, when do you think that Blast furnace cooling waters were released to the docks. My understanding is that only Power Station and Power Plant cooling waters were released to the freshwater docks and these only as secondary coolants.
These so called facts need to be substantiated or they could be libelous. I still maintain this part of the paragraph should be deleted until the causal link substantiated.

replies: text: I have changed the words steel works to iron works in the relevant para for greater clarity. Up until the late 1970, all the waste waters from blast furnaces 1, 2 and 3 ran directly into the docks and hence the Ffrwdwyllt. The docks also provided the cooling water for the power station although by the 1970s, the clean water feed for water supply at the works came from Eglwys Nunydd via the water treatment plant built to supply the rolling mills. There is of course no question of libel here. The discharges were not illegal (as noted above) and were acknowledged by British Steel management  Velella  Velella Talk   06:14, 4 May 2011 (UTC)

text: The Ffrwdwyllt flow mixes with part of the Afan flow in the docks and smolts travelling down the Afan got trapped in the docks and were exposed to the waste waters from the blast furnaces. Do I have evidence for that ? Well yes I now do courtesy of the Environment Agency and its retention of the old NRA data and the data from the previous Glamorgan River Division. Once I can get it into a form suitable for Wikipedia I will upload it. I don't invent facts  but I do regret the behaviour of editors who delete first and ask questions later. As for old industries in the Afan valley, can you point to any ? By the 1970's the collieries were mostly closed and, except for sewage, the Afan was remarkably clean except of course for the iron rich waters of the Pelena.  Velella  Velella Talk   22:52, 24 July 2011 (UTC)

text: As you note the Afan flows into the docks and out again through the dock gates. I have never written anything to the contrary. The docks are thus part of the course of the Afan and the confluence with the Ffwrdwyllt is actually within the docks. As to the pollution laws, which one would you like me to cite ? The River (prevention of Pollution) acts 1951 - 1961  which were in force at the time I was discussing - well yes, they would have proscribed the discharge of cyanide unless such discharge was covered by a Consent to Discharge issued by The Welsh National Water Development Authority or any of its predecessors, the Glamorgan River Authority or the Glamorgan River Board. However if it had a prescriptive right enshrined in law by some private piece of legislation or if the discharge in question was a type specifically exempted by the 51-61 Acts then no offence would be committed. It can be surprising to wade through the appendices to these acts to discover what is exempt and why, for example, Coal mines continued discharging their waste uncontrolled until 1974. For the record I do know the answer to all these questions , however my enthusiasm for finding reliable sources is fast diminishing and, as the sources will be in the public domain, you are welcome to try and find them.  Velella  Velella Talk   19:38, 26 July 2011 (UTC)
