More than one attribute.

[=?Utf-8?B?RGF2ZQ==?=]

you can write
writer.WriteStartElement("data", "http://www.w3.org/1999/XMLSchema-instance");

in your code for,

<data xmlns="http://www.w3.org/1999/XMLSchema-instance">

how do you write,

<data xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="../documents/xml/epic.xsd">

for two attributes?

Note that the official W3C schema instance URI is
http://www.w3.org/2001/XMLSchema-instance.

As for writing attributes, in case of a namespace declaration like
xmlns:xsi="..." you don't need to write it at all, it suffices to write
the attribute in that namespace:
const string xsi = "http://www.w3.org/2001/XMLSchema-instance";
using (XmlWriter writer = XmlWriter.Create(Console.Out))
{
writer.WriteStartElement("data");
writer.WriteAttributeString("xsi",
"noNamespaceSchemaLocation", xsi, "../documents/xml/epic.xsd");
writer.WriteEndElement();
}

If you want to explicitly write the namespace declaration, then that is
possible too:

const string xsi = "http://www.w3.org/2001/XMLSchema-instance";
using (XmlWriter writer = XmlWriter.Create(Console.Out))
{
writer.WriteStartElement("data");
writer.WriteAttributeString("xmlns", "xsi",
"http://www.w3.org/2000/xmlns/", xsi);
writer.WriteAttributeString("xsi",
"noNamespaceSchemaLocation", xsi, "../documents/xml/epic.xsd");
writer.WriteEndElement();
}

Thanks, that exactly what I needed.

One more question, the customer where we're sending the files to says they
can't read double quotes around attributes, is there a way to specify single
quotes?

XML allows both double and single quotes, if you have agreed to exchange
XML then whoever consumes that should be able to deal with double quotes.

If you really want to change that then you will need to use
XmlTextWriter and set its QuoteChar property as needed:
XmlTextWriter writer = new XmlTextWriter("file.xml", Encoding.UTF8);
writer.QuoteChar = '\'';
